Add support for the STM32F4 CRC32

This patch series add hardware CRC32 ("Ethernet") calculation support for STMicroelectronics STM32F429.

Polynomial and key setting are not supported, key is fixed as 0x4C11DB7 and poly is 0xFFFFFFFF.

Module is tested on STM32F429-disco board with crypto testmgr using cases within the key 0xFFFFFFFF.

Changes in v3:
Rearranged patch order to fix build test error.
