rk3288: Fix failing LPDDR3 reboot test
tMRD request 10nCK in LPDDR3, we set the DDR_PCTL_TMRD BIT0~BIT2 to generate
this signal, but the max value we can set is 7, so the standard can not be met.
So, now we send the Mode Register Set command manually, and hence we can add
the delay manually.
BUG=chrome-os-partner:34608
TEST=loop reboot
BRANCH=veyron
