This commit enables clock control on the i.MX8QM and QXP boards.
This is achieved through the following changes:
1) The "reg" property is no longer marked as required
for the "nxp,imx-ccm" binding. This is necessary because
in the case of i.MX8QM and i.MX8QXP the clock management
is done through the SCFW, hence there's no need to access
CCM's MMIO space (not that you could anyways).
2) The DTS now contains a scu_mu node. This node refers
to the MU instance used by the DSP to communicate with
the SCFW.
3) The CCM driver needs to support the LPUART clocks
(which will be the only IP that's supported for now)
and needs to perform an initialization so that the
NXP HAL driver knows which MU to use to communicate
with the SCFW.

the HSI48 clock is the clock used by default for the USB controller,
however its default tolerance is not enough for the USB specification,
leading to some random errors depending on many factors, including the
upstream HUB or host.

Latency should be set before HCLK clock increase. Not doing so can result
in broken behavior.
For instance, at startup, MSI is @4MHz on L4 series.
If MSI is required to be configured at 48 MHz for future use a USB clock,
this will be done in set_up_fixed_clock_sources(). If flash latency is
not correctly set at this point fetching flash will fail..

It is possible that stm32_clock_control_init function is started

Add clock control support for UART controllers found in i.MX SoC family.
This change moves clock gating out of respective `soc.c` files and into
clock controller's `clock_control_on`/`_off` methods, allowing for
dynamic clock state control, and setup via Device Tree bindings.
This is especially important on SoCs, where Zephyr is sharing the bus
with cores running other OSes, such as might be the case for i.MX 8MM.
Unfortunately, Zephyr doesn't possess an ability to represent clock
hierarchy (e.g. via DT's `assigned-clocks` property), so clock source
and frequency still need to be hardcoded in aforementioned `soc.c`
files.
