Since the regmap of rtc on sa1100, pxa and mmp Marvell soc families are
almost the same, so re-arch the rtc-sa1100 to support them.

Err. ?This looks wrong. ?What's the clk stuff doing in here? ?It seems
to be completely unused by the driver, and then both PXA and SA1100
end up having to provide a 'dummy' clk structure to satisfy this
additional useless code.

If it's a case that "every driver must use a clk" then there's a policy
error somewhere.

Since this RTC driver could be shared among sa1100, pxa, mmp. In
sa1100 and pxa3xx, we don't have this clock. So we use dummy clock
instead. For pxa95x and mmp series, we have this clock.
