MLK-11281-1 ARM: imx7d: add lpsr resume support for imx7d

For imx7d 12x12-lpddr3-arm2 board, when system enters LPSR
mode and waked up, ARM core will be reset and uboot needs to be
executed first, the LPSR register contains a resume entery,
if this entry is non-zero, then it means it is a resume from
LPSR mode, uboot plug in code needs to make DRAM exit from
retention mode then jump to the entry directly, otherwise,
it is a cold boot, normal boot process will be performed.
