[PATCH] clk: clk-imx8mm: Initialize clocks in arch_initcall

[Paul Geurts]

The i.MX8MM clock driver is implemented as module_platform_driver();,
which makes it initialize in device_initcall(). This means that all
drivers referencing the clock driver nodes in the device tree are
deferred by fw_devlink, which are most of the i.MX8M platform drivers.

Explicitly initialize the clock driver in arch_initcall(), to make sure
the clock driver is ready when the rest of the drivers are probed.
