Ahmad Fatoum 06a61b5cb6 clk: imx8mp: inform CCF of maximum frequency of clocks 
The IMX8MPCEC datasheet lists maximum frequencies allowed for different
modules. Some of these limits are universal, but some depend on
whether the SoC is operating in nominal or in overdrive mode.

The imx8mp.dtsi currently assumes overdrive mode and configures some
clocks in accordance with this. Boards wishing to make use of nominal
mode will need to override some of the clock rates manually.

As operating the clocks outside of their allowed range can lead to
difficult to debug issues, it makes sense to register the maximum rates
allowed in the driver, so the CCF can take them into account.
