MCK1 feeds the External Bus Interface (EBI). EBI's clock rate is used
to translate EBI's timmings to SMC timings, thus we need to handle MCK1
in the EBI driver. Allow MCK1 to be referenced as a PMC_TYPE_CORE clock
from phandle in DT.

Make AUDIOPINCK accessible via phandle to select it
as peripheral clock parent using assigned-clock-parents in DT
where available.

Register CPU clock as being the master clock prescaler. This would
be used by DVFS. The block schema of SAMA7G5's PMC contains also a divider
between master clock prescaler and CPU (PMC_CPU_RATIO.RATIO) but the
frequencies supported by SAMA7G5 could be directly received from
CPUPLL + master clock prescaler and the extra divider would do no work in
case it would be enabled.

We need to have clocks accessible via phandle to select them
as peripheral clock parent using assigned-clock-parents in DT.
Add support for PLLACK/PLLBCK/AUDIOPLLCK clocks where available.

Most of the clock related dt-binding header files are located in
dt-bindings/clock folder. It would be good to keep all the similar
header files at a single location.
