clk: at91: allow configuring peripheral PCR layout
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.
