Zephyr v2.4.0 added a const qualifier to usages of struct device to
allow storing device driver instances exclusively in flash and thereby
reduce ram footprint.

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.

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.

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.
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.
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.
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.
