fix(h5): review system clock configuration
SPI clock selection have to be explicitly done and ensure frequency allows standard SPI freq based on the SPI baudrate prescaler. Also prevent to use HSE as it is not operational as oscillator. See Errata sheet. Fixes #2598 Signed-off-by: Frederic Pillon <[email protected]>
