8f9f6ba855 imx8m: ddr: Disable CA VREF Training for LPDDR4
Users reported LPDDR4 MR12 value is set to 0 during PHY training,
not the value from FSP timing structure, which cause compliance test failed.
The root cause is the CATrainOpt[0] is set to 1 in 2D FSP timing
but not set in 1D.  According to PHY training application node,
to enable the feature both 1D and 2D need set this field to 1,
otherwise the training result will be incorrect.
The PHY training doc also recommends to set CATrainOpt[0] to 0 to use
MR12 value from message block (FSP structure). So update the LPDDR4
scripts of all mscale to clear CATrainOpt[0].

3f63d27c17 imx8mp: Disables use of MR4 TUF flag (MR4[7]) bit
In uMCTL2 Databook, for LPDDR4, it is recommended to set
this register to 1. This can avoid ddr bandwidth is lower
after booting with running for a while.
