Add CRC Driver
This patch includes a high level and two low level drivers.
The high level driver is enabled with flag HAL_USE_CRC
The low level drivers include:
* Hardware CRC for the STM32 cortex processor lines.(when supported)
* Enabled with flag STM32_CRC_USE_CRC1
* DMA is enabled with CRC_USE_DMA
* SYNC api will use DMA, but put calling thread to sleep
* ASYNC api enabled.
* DMA Disabled
* SYNC api spin while calculating CRC
* ASYNC api disabled
* Software CRC (3 modes)
* CRCSW_CRC32_TABLE - Enables crc32 with lookup table.
* CRCSW_CRC16_TABLE - Enables crc16 with lookup tables.
* CRCSW_PROGRAMMBLE - Enables any crc done with computation.
* Can calculate any crc configuration.
* CRC_USE_DMA obviously not support with software CRC
