Correct STM32MP13 clock gates initialization regarding the enable
reference counting. The fixed commit introduced side effect where
clock gates with a disable init state overflow the gate refcount to -1
and clock gates with a enable init state take a refcount that is never
released.
For this purpose, add stm32_gate_set_init_state() function in
stm32 clock core driver for STM32MP13 gate clocks initialization
expects to set some clock gate hardware state (enabled or disabled)
before any refcount is considered.
Fixes: 2b028a2ba197 ("clk: implement multi-gate management at core level")
