Save and restore the System Clock and Programmable Clock register for
the backup use case.

"System Clock" seems to be handled in another patch.

Some products have different numbers of PCK (only 2 on at91sam9x5 for
instance)...

My opinion is that it will be time to change that when multiple SoCs will
need to save their registers.

For the next version, I'll add a #define. But as this code requires a
device tree node with the compatible string "atmel,sama5d2-pmc", I believe
that we can ignore other chips for now.

Fair enough, let's go for this.
