Add a minimal support for STM32MP13 RCC, the reset and clock controller - update of the RCC MISC driver to bind the correct clock and reset driver - reset driver, same than STM32MP15x = drivers/reset/stm32-reset.c - clock driver, add a empty driver for STM32MP13x = drivers/clk/stm32/clk-stm32mp13.c - Add RCC node in SOC device tree with u-boot,dm-pre-reloc property
This serie is only a preliminary step for STM32MP13 clock and reset support in U-Boot, based on Linux kernel binding introduced by [1] and it prepares the next device tree alignment with Linux kernel.
The functional STMP13 clock driver based on CCF and on SCMI clocks provided by OP-TEE and the clock and reset references in SOC device tree will be pushed when the associated patches in [1] will be accepted.
