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
dram frequency.
