Unlike rest of dram type chips, LPDDR4 initialization start
with at board selected frequency (say 50MHz) and then it
switches into 400MHz and 800MHz simultaneously to make the
proper sequence work on each channel with associated training.
The lpddr4 set rate sequnce will follow by setting lpddr4
- dq out
- ca odt
- MR3
- MR12
- MR14

Here is sameple log about LPDDR4-100 init sequence in Rockpro64:

It is possible in lpddr4 dram, where both the channels would
start at same time with ZQ Cal Start. If it uses ZQ Call start
then it will use RZQ.
For example LPDDR4 366 Dual-Die, Quad-Channel Package, RZQ maybe
connect to both channel. If ZQ Cal Start at the same time,
it will use the same RZQ.
It is not a problem of using RZQ in both the channels, but can not
use at the same time.
So, to avoid this, we have an option of dram tINIT3 value for
increasing the frequency for channel 1.
This patch increase the available tINIT3 with existing running
