Rob Herring e66ce07a96 ARM: config: Switch PXA27x platforms to use PXA RTC driver 
With the SA1100 and PXA RTC drivers be mutually exclusive and no
longer sharing hardware, PXA27x/PXA3xx platforms must use the PXA RTC
driver as the SA1100 platform device is no longer registered.

This change should be almost transparent to userspace. Former users of
pxa-rtc should be aware that 2 RTCs will be available on their kernels,
rtc0 being sa1100-rtc and rtc1 being pxa-rtc. Any userspace relying on
the fact that rtc0 was pxa-rtc should be fixed.

As a consequence:
 - the first reboot after the switch will have the wrong time,
 - on dual boot platform where the other OS programs some logic into the
   sa1100 rtc IP, a lack of fix in userspace, ie. a kernel changing
   sa1100-rtc thinking it is pxa-rtc could have dire consequence, such
   as wiping the other OS data partition.

(Thanks to Robert Jarmik for help on the above commit text.)
