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.

5d2279bec1 extmod/machine_i2c: Add hook to constructor to call port-specific code. 
If MICROPY_PY_MACHINE_I2C_MAKE_NEW is defined then it is called when an
I2C object is constructed with an id which is not -1.

13400e1375 stmhal/hal: do not include <stdio.h> in HAL headers 
stdio.h was included in all HAL files only to provide
definition of NULL symbol

"stdio.h" includes "types.h" which contains some conflicting definitions
with "drivers/cc3000/inc/socket.h"

7604de3fc2 stmhal/can: clear FIFO flags in IRQ handler 
HAL Driver before v1.4.2 had a bug which caused clearing all pending
flags in MSR, TSR, RF0R and RF1R instead of only the requested one.

This is why micropython got away without explicitly clearing flags
in IRQ handler.

dc1ac5dc3a stmhal/dma: mark DMA sate as READY even if HAL_DMA_Init is skipped

63ca7a211a stmhal/dma: precalculate register base and bitshift on handle init 
Current version of HAL drivers optimize IRQ handler by using precalculated
DMA register address and stream bitshift instead of calculating it on every interrupt.

Since we skip call to `HAL_DMA_Init` on reused DMA, fields StreamBaseAddress and StreamIndex
of DMA handle are not initialized and thus leads to SegFault in `DMA_IRQHandler`.

HAL_DMA_Init is a big routine and we do not need to call it on each use of DMA
(ex.: series of I2C operations) and DMA_CalcBaseAndBitshift is really small and
releasing it increases code size by only 8 bytes.
