The clk count has been get with of_clk_get_parent_count, there is
no need to pass clk_count from users.

The clock driver is registered as platform devices and
it is possible to reloading the driver at runtime.
But actually the clocks should never be removed to make system work,
attempting to bind again would result in a crash, because almost all
devices depends on clock to function well.

On i.MX8ULP, for some of the PCCs, it has a peripheral SW RST bit
resides in the same registers as the clock controller. So add this
SW RST controller support alongs with the pcc clock initialization.
the reset and clock shared the same register, to avoid accessing
the same register by reset control and clock control concurrently,
locking is necessary, so reuse the imx_ccm_lock spinlock to simplify
the code.
