Contrib: RCC controls for CRC Topic is solved

[kimmoli]

Using Hardware CRC from Chibios-Contrib needs rcc control functions for CRC peripheral. These are missing from stm32_rcc.

< barthess> kimmoli: there is no place for RCC stuff in contrib. Create topic on forum with patch attached.

Propsed patch will add them:

Is this change F4-specific?

Added to the F4 only for the time being.
