Create a new linker section .unitialized_bss for bss that does not need
zero-initialising.
Move gc_heap to this section, which saves ~30ms from rising edge of RESET
to setting a pin HIGH in MicroPython.
Zero fill happens in Pico SDK crt0.S before ROSC is configured. It's very,
very slow.

The ntptime module was previously only included in the ESP8266 port. This
commit factors that module out into the extmod directory, makes it support
different epochs, and includes it in the rp2 port.
Used to be special-cased for Pico, but now everything depends on
micropython-lib if it's using a frozen manifest.

Still see some USB issues apparently caused by delays loading wifi
firmware. cyw43_delay_ms is used to wait in the driver, so we should call
the event hook in there.
Fixes#8963.
The state machines were not properly restarted in the case that the same
PIO program was shared among multiple StateMachine instances. This is
because only the first StateMachine to use the program would set the
rp2_state_machine_initial_pc variable.

This is a statically-allocated UART (see machine_uart.c), and doesn't
contain any heap pointers other than the ringbufs (which are already root
pointers), so no need to track it additionally.
Saves needing to add mpbthciport.c to the QSTR sources.

rp2: change tud_task() to tud_task_ext().
mimxrt: use lib/tinyusb/src/portable/chipidea/ci_hs/dcd_ci_hs.c instead of
lib/tinyusb/src/portable/nxp/transdimension/dcd_transdimension.c.
nrf: add a definition for the changed tud_task(). tud_task() is changed
to tud_task_ext(), and the #define for backward compatibility is in
src/device/usbd.h.
The items I know which are fixed with this version:
- Fix for the SAMD USB lock-up.
- Support the MIMXRT11XX series of MCUs.
- Fix a wrong pin definition for MIMXRT1050_EVKB.
Tested with the MIMXRT boards, rp2 Pico, SAMD boards, nrf board.
All ports that use mbedtls use the custom error messages in
mp_mbedtls_errors.c. This commit simplifies the build so that ports don't
need to explicitly add this file, it's now used by default when mbedtls is
enabled.

All in-tree uses of MICROPY_PORT_ROOT_POINTERS have been replaced with

When a flash write/erase is in progress, we need to ensure that the
other core cannot be using XIP.
This also implements MICROPY_BEGIN_ATOMIC_SECTION as a full mutex, which
is necessary as it's used to syncronise access to things like the scheduler
queue.

The goal is to avoid a situation where core 1 is shut down while holding
the tinyusb spinlock, which could happen during soft reset if
mp_thread_deinit is called while core1 is running tud_task().
This also fixes a latent race where the two cores are competing to
decrement and compare `vm_hook_divisor` with no mem fence or atomic
protection -- only core0 will now do this.

Ensure that nimble and cyw43-driver are initialised when the board requires
it. Also make these work with `make submodules`.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
This includes:
- Configuration file for the cyw43-driver.
- Integration of cyw43-driver into the build, using lwIP.
- Enhancements to machine.Pin to support extension IO pins provided by the
CYW43xx.
- More mp-hal pin helper functions.
- mp_hal_get_mac_ascii MAC address helper function.
- Addition of rp2.country() function to set the country code.
A board can enable this driver by setting MICROPY_PY_NETWORK_CYW43 in their
cmake snippet.

This gets basic machine.lightsleep([n]) behaviour working on the rp2 port.
It supports:
- Calling lightsleep without a specified period, in which case it uses xosc
dormant mode. There's currently no way to wake it up from this state,
unless you write to raw registers to enable a GPIO wake up source.
- Calling lightsleep with a period n in milliseconds. This period must be
less than about 72 minutes and uses timer alarm3 to wake it up.
The RTC continues to run during lightsleep, but other peripherals have
their clock turned off during the sleep.
It doesn't yet support longer periods than 72 minutes, or waking up from
GPIO IRQ.
Measured current consumption from the USB port on a PICO board is about
1.5mA when doing machine.lightsleep(5000), and about 0.9mA when doing
machine.lightsleep().
Addresses issue #8770.

The following changes are made:
- Guard entire file with MICROPY_PY_LWIP, so it can be included in the
build while still being disabled (for consistency with other extmod
modules).
- Add modlwip.c to list of all extmod source in py/py.mk and
extmod/extmod.cmake so all ports can easily use it.
- Move generic modlwip GIT_SUBMODULES build configuration code from
ports/rp2/CMakeLists.txt to extmod/extmod.cmake, so it can be reused by
other ports.
- Remove now unnecessary inclusion of modlwip.c in EXTMOD_SRC_C in esp8266
port, and in SRC_QSTR in mimxrt port.

Otherwise include directories are added unconditionally to the build
variables if the component (submodule) is checked out. This can lead to,
eg, the esp32 build using lib/lwip header files, instead of lwip header
files from the IDF.
