The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c. Enabling MICROPY_PY_MACHINE will include this
module.
As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

CONFIG_USB was removed in Zephyr v2.7.0 after some Kconfig rework that

Adds support for hardware SPI to the zephyr port. Consistent with other
ports, such as rp2 and stm32, we only implement the SPI protocol functions
(init and transfer). Explicit sck/mosi/miso selection is not supported
and new SPI instances are initialized with default values.
Currently only advertising and scanning are supported, using the ring
buffer for events (ie not synchronous events at this stage).
The ble_gap_advertise.py multi-test passes (tested on a nucleo_wb55rg
board).

Zephyr's default value for CONFIG_NET_SOCKETS_POSIX_NAMES was changed

conflicts in MicroPython, which uses the zsock_ prefixed functions, so
disable it.

The following simple usocket example throws an error EINVAL on connect
import usocket
s = usocket.socket()
s.connect(usocket.getaddrinfo('www.micropython.org', 80)[0][-1])
Traceback (most recent call last):

OSError: [Errno 22] EINVAL
Fixing the context parameter in calls of net_context_get_family() and
net_context_get_type(), the connect works fine.

Refactors the zephyr build infrastructure to build MicroPython as a
cmake target, using the recently introduced core cmake rules.
This change makes it possible to build the zephyr port like most other
zephyr applications using west or cmake directly. It simplifies building
with extra cmake arguments, such as specifying an alternate conf file or
adding an Arduino shield. It also enables building the zephyr port
anywhere in the host file system, which will allow regressing across
multiple boards with the zephyr twister script.

The zephyr function net_shell_cmd_iface() was removed in zephyr v1.14.0,
therefore the MicroPython zephyr port did not build with newer zephyr
versions when CONFIG_NET_SHELL=y. Replace with a more general
shell_exec() function that can execute any zephyr shell command. For
example:
>>> zephyr.shell_exec("net")
Subcommands:
allocs :Print network memory allocations.
arp :Print information about IPv4 ARP cache.
conn :Print information about network connections.
dns :Show how DNS is configured.
events :Monitor network management events.
gptp :Print information about gPTP support.
iface :Print information about network interfaces.
ipv6 :Print information about IPv6 specific information and
configuration.
mem :Print information about network memory usage.
nbr :Print neighbor information.
ping :Ping a network host.
pkt :net_pkt information.
ppp :PPP information.
resume :Resume a network interface
route :Show network route.
stacks :Show network stacks information.
stats :Show network statistics.
suspend :Suspend a network interface
tcp :Connect/send/close TCP connection.
vlan :Show VLAN information.
websocket :Print information about WebSocket connections.
>>> zephyr.shell_exec("kernel")
kernel - Kernel commands
Subcommands:
cycles :Kernel cycles.
reboot :Reboot.
stacks :List threads stack usage.
threads :List kernel threads.
uptime :Kernel uptime.
version :Kernel version.

Hardware I2C implementations must provide a .init() protocol method if they
want to support reconfiguration. Otherwise the default is that i2c.init()
raises an OSError (currently the case for all ports).
mp_machine_soft_i2c_locals_dict is renamed to mp_machine_i2c_locals_dict to
match the generic SPI bindings.
Fixes issue #6623 (where calling .init() on a HW I2C would crash).

With a warning that this way of constructing software I2C/SPI is
deprecated. The check and warning will be removed in a future release.
This should help existing code to migrate to the new SoftI2C/SoftSPI types.

Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances. Such
construction is now split to explicit soft and non-soft types.
This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.
This is a breaking change for use of software-based I2C and SPI. Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:
machine.I2C(-1, ...) -> machine.SoftI2C(...)
machine.I2C(scl=scl, sda=sda) -> machine.SoftI2C(scl=scl, sda=sda)
machine.SPI(-1, ...) -> machine.SoftSPI(...)
machine.SPI(sck=sck, mosi=mosi, miso=miso)
-> machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)
Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

Supports hard and soft interrupts. In the current implementation, soft
interrupt callbacks will only be called when the VM is executing, ie they
will not be called during a blocking kernel call like k_msleep. And the
behaviour of hard interrupt callbacks will depend on the underlying device,
as well as the amount of ISR stack space.
Soft and hard interrupts tested on frdm_k64f and nucleo_f767zi boards.
