clk: imx8mm: Switch to platform driver

Browse Source 
There is no strong reason for this to use CLK_OF_DECLARE instead
of being a platform driver. Plus, this will now be aligned with the
other i.MX8M clock drivers which are platform drivers.

In order to make the clock provider a platform driver
all the data and code needs to be outside of .init section.
