Damien George f523b86541 extmod/modmachine: Provide common implementation of disable/enable_irq.
The ports esp32, mimxrt, rp2 and samd all shared exactly the same
implementation of machine.disable_irq() and machine.enable_irq(),
implemented in terms of MICROPY_{BEGIN,END}_ATOMIC_SECTION.  This commit
factors these implementations into extmod/modmachine.c.

The cc3200, esp8266, nrf, renesas-ra and stm32 ports do not yet use this
common implementation.

Damien George e1ec6af654 extmod/modmachine: Provide common bindings for 6 bare-metal functions.
Minor changes for consistency are:
- nrf gains: unique_id(), freq() [they do nothing]
- samd: deepsleep() now resets after calling lightsleep()
- esp32: lightsleep()/deepsleep() no longer take kw arg "sleep", instead
  it's positional to match others.  also, passing 0 here will now do a 0ms
  sleep instead of acting like nothing was passed.
  reset_cause() no longer takes any args (before it would just ignore them)
- mimxrt: freq() with an argument and lightsleep() both raise
  NotImplementedError

Damien George e68aa40d2a extmod/modmachine: Add MICROPY_PY_MACHINE_PIN_BASE option.
And use it in qemu-arm, unix and windows ports to enable PinBase.

Damien George 30a63a204d extmod/modmachine: Provide common Python bindings for machine.idle().
And use it in all ports.  The ports are unchanged, except esp8266 which now
just returns None from this function instead of the time elapsed (to match
other ports), and qemu-arm which gains this function.

Damien George 7d39db2503 extmod/modmachine: Factor ports' machine module dict to common code.
This is a code factoring to have the dict for the machine module in one
location, and all the ports use that same dict.  The machine.soft_reset()
function implementation is also factored because it's the same for all
ports that did already implement it.  Eventually more functions/bindings
can be factored.

All ports remain functionally the same, except:
- cc3200 port: gains soft_reset, mem8, mem16, mem32, Signal; loses POWER_ON
  (which was a legacy constant, replaced long ago by PWRON_RESET)
- nrf port: gains Signal
- qemu-arm port: gains soft_reset
- unix port: gains soft_reset
- zephyr port: gains soft_reset, mem8, mem16, mem32

Dave Hylands f925165942 unix: Move modmachine into unix directory
This leaves behind the common functionality in extmod/machine_mem.c
which can be used by all ports.

Damien George 999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.

This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.

Paul Sokolovsky 354d17523f modmachine: Implement physical memory access using /dev/mem (Linux, etc).
This requires root access. And on recent Linux kernels, with
CONFIG_STRICT_DEVMEM option enabled, only address ranges listed in
/proc/iomem can be accessed. The above compiled-time option can be
however overriden with boot-time option "iomem=relaxed".

This also removed separate read/write paths - there unlikely would
be a case when they're different.
