rtc: sa1100: prepare to share sa1100_rtc_ops Factor out the RTC initialization from the platform device specific parts in order to share the RTC device ops with other drivers. Specifically, it will be shared with rtc-pxa driver.

rtc: sa1100/pxa: convert to run-time register mapping SA1100 and PXA differ only in register offsets which are currently hardcoded in a machine specific header. Some arm64 platforms (PXA1928) have this RTC block as well (and not the PXA270 variant). Convert the driver to use ioremap and set the register offsets dynamically. Since we are touching all the register accesses, convert them all to readl_relaxed/writel_relaxed.
