rtc: stmp3xxx: Restore register definitions
Wolfram Sang [Wed, 25 May 2011 10:56:49 +0000 (12:56 +0200)]
The stmp3xxx driver used to include register names from a stmp-specific
include. Because of consolidation, plat-stmp has now been removed and
merged with the compatible mach-mxs. Restore the register names directly
in the driver and rename them to be specific to this driver.
