Derek Basehore 951752dd6c rockchip: rk3399: Save and restore RX_CAL_DQS values
We were getting far off values on resume for the RX_CAL_DQS values.
This saves and restores the values for suspend/resume until the root
of the problem is figured out

Derek Basehore 4bd1d3faed rockchip: rk3399: add support for ddrfreq suspend/resume
This patch sets the frequency configuration of the next DRAM DFS index
to the configuration of the current index. This does not perform a
frequency transition. It just configures registers so the training on
resume for both indices will be correct.
