This patch series is NOT related to 'assigned-clock' or 'assigned-clock-rates'
property, it is just for correcting clock source according to reference manual,
the 'ipg' clock is from system's IPG_ROOT clock according to reference manual CCM
chapter, using DUMMY clock is NOT a good option, the 'ipg' clock is supposed
to be the clock for accessing register, and it should NOT be DUMMY if we know
what exactly the clock source is used.

Thanks,
Anson
