08bd7d1d31 stmhal/sdcard: Clean/invalidate cache before DMA transfers with SD card. 
Add 2 macros in mphalport.h that clean and invalidate data caches only on
STM32F7 MCUs.  They are needed to ensure the cache coherency before/after
DMA transferts.

* MP_HAL_CLEANINVALIDATE_DCACHE cleans and invalidate the data cache. It
  must be called before starting a DMA transfer from the peripheral to the
  RAM memory.

* MP_HAL_CLEAN_DCACHE cleans the data cache.  It must be called before
  starting a DMA transfert from the RAM memory to the peripheral.

These macros are called in sdcard.c, before reading from and writing to
the SDCard, when DMA is used.

a081b49d55 extmod/modframebuf: Optimise fill and fill_rect methods. 
Fill is a very common operation (eg to clear the screen) and it is worth
optimising it, by providing a specialised fill_rect function for each
framebuffer format.

This patch improved the speed of fill by 10 times for a 16-bit display
with 160*128 pixels.

81e171b7bb extmod/modframebuf: Add back legacy FrameBuffer1 "class". 
For backwards compatibility.  It simple creates a frame buffer with the
MVLSB format.

225e22b287 extmod/modframebuf: Make FrameBuffer handle 16bit depth. 
Rename FrameBuffer1 into FrameBuffer and make it handle different bit
depths via a method table that has getpixel and setpixel.  Currently
supported formats are MVLSB (monochrome, vertical, LSB) and RGB565.

Also add blit() and fill_rect() methods.

c19a395cac stmhal/adc: Make channel "16" always map to the temperature sensor. 
The temperature sensor on F4 and F7 MCUs is mostly, but not always, on
channel 16.  To retain compatibility across all these MCUs this patch
maps the user-facing channel 16 to the internal temperature sensor.

e72353cc48 stmhal/adc: Make ADCAll.read_core_temp return accurate float value. 
It now uses factory calibration values to get a more accurate value, and
returns a float instead of an integer.

029f215ead stmhal/adc: Add "mask" selection parameter to pyb.ADCAll constructor. 
The "mask" parameter is used to select which pins the ADCAll constructor
will initialise to analog mode.  It defaults to all pins (0xffffffff),
which is backwards compatible with previous behaviour.

139b891d6d stmhal: Add back GPIO_BSRRL and GPIO_BSRRH constants to stm module. 
These were inadvertently removed with a recent upgrade to CMSIS, where
those registers were no longer defined in the CMSIS headers, and hence
no longer extracted.

3053748987 stmhal: Add beginnings of port-specific machine.I2C implementation. 
This allows one to construct an I2C object using ids that are specific
to the stmhal port, eg machine.I2C('X').  Right now the implementation
of I2C uses software I2C but the idea is to just change the C-level I2C
protocol functions to hardware implementations later on.
