6e0ca0658e ddr: imx: Handle both 3733 and 3732 MTps rates 
The DDR calibration tool for i.MX8M currently produces 3732 MTps rate in
lpddr4_timing.c , while the PHY code expects 3733 MTps rate. Support both
variants to avoid surprises where the system fails to boot.

99c7cc58e1 ddr: imx: Add i.MX9 DDR controller driver 
Since i.MX9 uses same DDR PHY with i.MX8M, split the DDRPHY to a common
directory under imx, then use dedicated ddr controller driver for each
iMX9 and iMX8M.

The DDRPHY registers are space compressed, so it needs conversion to
access the DDRPHY address. Introduce a common PHY address remap function
for both iMX8M and iMX9 for all PHY registers accessing.
