drivers: clk: stm32: fix stm32mp13 clock gates initialization

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.

clk: implement multi-gate management at core level

The majority of all peripherals have their bus and kernel clocks with
the same clock gating register bit. Therefore it is mandatory to handle
a counter on the gates.
