Ludovic Desroches 92041a9ff0 clk: at91: utmi: set the mainck rate
By default, it is assumed that the UTMI clock is generated from a 12 MHz
reference clock (MAINCK). If it's not the case, the FREQ field of the
SFR_UTMICKTRIM has to be updated to generate the UTMI clock in the
proper way.

The UTMI clock has a fixed rate of 480 MHz. In fact, there is no
multiplier we can configure. The multiplier is managed internally,
depending on the reference clock frequency, to achieve the target of
480 MHz.
