refactor(st-clock): move stm32mp1_clk_rcc_regs_*lock

Those functions are only used on MP1, they should not be in STM32 clock
core. Move them to MP13 driver (they are already in MP15 driver).
Redefine new clk_stm32_rcc_regs_*lock() functions in clock core. This
change avoid sparse warning:
drivers/st/clk/clk-stm32-core.c:46:6: warning: symbol
 'stm32mp1_clk_rcc_regs_lock' was not declared. Should it be static?
drivers/st/clk/clk-stm32-core.c:51:6: warning: symbol
 'stm32mp1_clk_rcc_regs_unlock' was not declared. Should it be static?
