e7332b0584 qemu-arm: Rework to run bare-metal on boards with Cortex-M CPUs. 
Adds support for 3 Cortex-M boards, selectable via "BOARD" in the Makefile:
- microbit, Cortex-M0 via nRF51822
- netduino2, Cortex-M3 via STM32F205
- mps2-an385, Cortex-M3 via FPGA

netduino2 is the default board because it's supported by older qemu
versions (down to at least 2.5.0).

1bcf4afb10 stm32/systick: Make periodic systick callbacks use a cyclic func table. 
Instead of checking each callback (currently storage and dma) explicitly
for each SysTick IRQ, use a simple circular function table indexed by the
lower bits of the millisecond tick counter.  This allows callbacks to be
easily enabled/disabled at runtime, and scales well to a large number of
callbacks.

f024b2610f extmod/moduhashlib: Include implementation of sha256 only when required. 
Previously crypto-algorithms impl was included even if MICROPY_SSL_MBEDTLS
was in effect, thus we relied on the compiler/linker to cut out the unused
functions.

1669e049de stm32/boards/STM32F769DISC: Configure for use with mboot by default. 
This is a good board to demonstrate the use of Mboot because it only has a
USB HS port exposed so the native ST DFU mode cannot be used.  With Mboot
this port can be used.

b26046aca2 stm32/modmachine: Make bootloader() enter custom loader if it's enabled. 
If a custom bootloader is enabled (eg mboot) then machine.bootloader() will
now enter that loader.  To get the original ST DFU loader pass any argument
to the function, like machine.bootloader(1).

98f790b03a nrf/timer: Fix disabling Timer 1 when using soft PWM. 
Don't exclude the Timer instance 1 entry from machine_timer_obj[] when
using soft PWM. The usage is already checked when creating the Timer,
so just create an empty entry.

1ba962ff57 nrf/uart: Remove unused machine.UART() parameters. 
If needed these parameters can be added back and made functional one at a
time.  It's better to explicitly not support them than to silently allow
but ignore them.

2f5d113fad py/warning: Support categories for warnings. 
Python defines warnings as belonging to categories, where category is a
warning type (descending from exception type). This is useful, as e.g.
allows to disable warnings selectively and provide user-defined warning
types.  So, implement this in MicroPython, except that categories are
represented just with strings.  However, enough hooks are left to implement
categories differently per-port (e.g. as types), without need to patch each
and every usage.

86f06d6a87 stm32/sdcard: Don't use SD clock bypass on F7 MCUs. 
With clock bypass enabled the attached SD card is clocked at the maximum
48MHz.  But some SD cards are unreliable at these rates.  Although it's
nice to have high speed transfers it's more important that the transfers
are reliable for all cards.  So disable this clock bypass option.
