[U-Boot] [PATCH] powerpc/t104xrdb: Toggle deep sleep management signals after resume

[Tang Yuantian]

From: Tang Yuantian <yuantian.tang at freescale.com>

T104xrdb has several sleep management signals that are used for deep
sleep. They are enabled by OS to enter deep sleep and should be
disabled by u-boot when cores wake up.
