Damien George 3ff7079277 lib/utils/mpirq: Add mp_irq_init func, and clean up unused init method.
mp_irq_init() is useful when the IRQ object is allocated by the caller.

The mp_irq_methods_t.init method is not used anywhere so has been removed.

Damien George f84145bea1 zephyr: Implement machine.Pin.irq() for setting callbacks on pin 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.

Maureen Helm 76a5b3a97a zephyr: Update machine.Pin class to use new zephyr gpio api.
Zephyr v2.2 reworked its gpio api to support linux device tree bindings and
pin logical levels.  This commit updates the zephyr port's machine.Pin
class to replace the deprecated gpio api calls with the new supported gpio
api.  This resolves several build warnings.

Tested on frdm_k64f and mimxrt1050_evk boards.

Maureen Helm c25e12d0dd zephyr: Update include paths for Zephyr v2.0.
Zephyr restructured its includes in v2.0 and removed compatibility shims
after two releases in commit 1342dadc365ee22199e51779185899ddf7478686.
Updates include paths in MicroPython accordingly to fix build errors in
the zephyr port.

These changes are compatible with Zephyr v2.0 and later.

Damien George a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.

Damien George 01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
