[U-Boot] OMAP4/Panda: u-boot upgrade v2012.04.01 -> v2012.10 breaks RTC wakeups

Hi Kevin,
In the latest, pad mux and clocks for all
non-essential modules at U-BOOT were removed.

This might also cause the problem.
We can bring this back in u-boot by adding the following macros
and check if it works fine again.

include/configs/omap4_common.h
------------------------------
#define CONFIG_SYS_ENABLE_PADS_ALL
#define CONFIG_SYS_CLOCKS_ENABLE_ALL

Regards,
Sricharan
