circuitpython/stmhal/hal/f4/inc/stm32f4xx_hal_rcc.h
Damien George e4d43401eb stmhal: Move HAL Cube files to f4/ subdir, keeping only those we use. 
This is in preparation for supporting other MCU series, such as
STM32F2xx.  Directory structure for the HAL is now hal/f4/{inc,src},
where "f4" will in the future be different for other series.

HAL source/header files that are not use are removed to reduce the size
of the code.
