Refer to the commit 70f8c8316ad(PMC: add new mck function to lower rate while switching) from AT91Bootstrap. While switching to a lower clock source, we must switch the clock source first instead of last. Otherwise, we could end up with too high frequency on internal bus and peripherals. This happens on SAMA5D2 as exitting from the ROM code. Add a function pmc_mck_init_down() to allow this sequence.
