ARM: pxa: add memory resource to SA1100 RTC device

The drivers for the SA1100 and PXA RTCs are now mutually exclusive, so
add the memory resource for the sa1100-rtc device. Since the memory
resource is already present in the pxa_rtc_resources, that makes
sa1100_rtc_resources and pxa_rtc_resources equivalent, so use
pxa_rtc_resources for both devices and remove the duplicate
sa1100_rtc_resources.
