Note that Sashiko skipped reviewing this patch, because it exceeded
its current 10000 line limit.

This drops the layout switch but keeps "mrvl,sa1100-rtc" in
sa1100_rtc_dt_ids[] and in bindings/rtc/sa1100-rtc.yaml, so a DT with
that compatible would now silently get the MMP register offsets instead
of the SA1100 ones.

"embedded into PXA2xx chips" is better.

The RTC_DRV_SA1100 help text a bit earlier in the patch also still says
"built into your SA11x0 or PXA2xx CPU".
