It's just some static data that doesn't get changed after being used.
Mark it const everywhere.

The PCR register actually changed layout for each SoC. By chance, this
didn't have impact on sama5d[2-4] support but since sama5d3, PID is seven
bits wide and sama5d4 and sama5d2 don't have DIV.
For the DT backward compatibility, keep the layout as is.

The master clock is actually named masterck earlier in the driver. Having
"mck" in the parent list means that it can never be selected.
