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].

There is a frequency/timing limitation for SOC and ARM, if SOC is OD
voltage/OD freq, then ARM can't run at ND voltage/1.2Ghz, it may have
timing risk from SOC to ARM.
Current VDD_SOC is set to 0.95v OD voltage in SPL, and kernel will
increase bus clocks to OD frequency before it increases ARM voltage.
So to conform to the limitation, we'd better increases VDD_ARM to OD
voltage in SPL.

When QEMU originally supported the ppce500 machine back in Jan 2014,
it was created with a 1:1 mapping of PCI bus address. Things seemed
to change rapidly that in Nov 2014 with the following QEMU commits:
commit e6b4e5f4795b ("PPC: e500: Move CCSR and MMIO space to upper end of address space")
and
commit cb3778a0455a ("PPC: e500 pci host: Add support for ATMUs")
the PCI memory and IO physical address were moved to beyond 4 GiB,
but PCI bus address remained below 4 GiB, hence a non-identity
mapping was created. Unfortunately corresponding U-Boot updates
were missed along with the QEMU changes and the U-Boot QEMU ppce500
PCI support has been broken since then.
This commit makes the PCI (non-DM version) work again.
