am335x_evm / gumstix pepper: Correct DDR settings
As noted by clang, we have been shifting certain values out of 32bit range when setting some DDR registers. Upon further inspection these had been touching reserved fields (and having no impact). These came in from historical bring-up code and can be discarded. Similarly, we had been declaring some fields as 0 when they will be initialized that way. Tested on Beaglebone White.
