MLK-13333-1 ARM: imx: correct i.mx6sll dram io low power mode

i.MX6SLL has different DRAM IO offset, and it has no
CAS/RAS/ODT/RESET pin now, correct the DRAM IO offset.

To better support all different i.MX6 SoCs and different
DRAM types, introduce a new column to store the low power
settings for DRAM IO, then suspend asm code no need to check
SoC or DRAM type, just get the DRAM IO's low power
settings from OCRAM pm_info and set to each DRAM IO.
