ram: rk3399: Add IO settings

Add IO settings for dram ctl and phy.

IO settings are useful for configuring ctl, phy odt, vref,
mr5, mode select and other needed input output operations
for lpddr4 or any other dramtype sdram.

Right now, this patch added IO setting for all supported
sdram frequencies.
