8e81e679db ddr: imx93: update the ddr init to support mult setpoints
Update the DDR init flow for multi-setpoint support on i.MX93. A new
fsp_cfg struct need to be added in the timing file to store the diff
part of the DDRC and DRAM MR register for each setpoint.

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.

23387416da ddr: imx8m: helper: load ddr firmware according to binman symbols
By reading binman symbols, we no need hard coded IMEM_LEN/DMEM_LEN after
we update the binman dtsi to drop 0x8000/0x4000 length for the firmware.

And that could save binary size for many KBs.

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.
