Wei Yongjun a1ea0857b5 clk: stm32: rcc_reset: Fix missing spin_lock_init()
The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

Gabriel Fernandez 637cee5ffc clk: stm32: Introduce STM32MP13 RCC drivers (Reset Clock Controller)
This driver manages Reset and Clock of STM32MP13 soc.
It uses a clk-stm32-core module to manage stm32 gate, mux and divider
for STM32MP13 and for new future soc.

All gates, muxes, dividers are identify by an index and information
are stored in array (register address, shift, with, flags...)
This is useful when we have two clocks with the same gate or
when one mux manages two output clocks.
