[ARM] pxa: stop doing our own rtc management over suspend
Remove the RTC management over a suspend/resume cycle. Firstly, we may not be using the internal RTC for time keeping; some platforms have an external RTC for this inspite of the PXA having an internal RTC. Secondly, the RTC library code handles updating system time on resume. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
