[PATCH v2 11/16] board: stm32pm1: add stm32mp13 board support

[Patrick Delaunay]

Add stm32mp15x prefix to all STM32MP15x board specific functions,
this patch is a preliminary step for STM32MP13x support.

This patch also adds the RCC probe to avoid circular access with
usbphyc probe as clk provider.
