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.

According to DDRPHY errata, the Rank-to-Rank Spacing and tphy_rdcsgap
specification does not include the Critical Delay Difference (CDD) to
properly define the required rank-to-rank read command spacing after
executing PHY training firmware.
Following the errata workaround, at the end of data training, we get
all CDD values through the MessageBlock, then re-configure the DDRC
timing of WWT/WRT/RRT/RWT with comparing MAX CDD values.

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.

To support on-demand booting M33 image from A core. SPL needs
to follow M33 kick up sequence to release M33 firstly,
then set M33 CPUWAIT signal. ATF will clear CPUWAIT to kick
M33 to run.
The prepare function also works around the M33 TCM ECC issue by
clean the TCM. Also enable sentinel handshake and WDOG1 clock
for M33 stop and reset.

i.MX93 fuse can be accessed through FSB and s400-api. Add mapping tables
for i.MX93. The offset address of FSB accessing OTP shadow registers is
different between i.MX8ULP and i.MX93, so use macro to define the offset
address instead of hardcode.

Add TRDC driver to iMX9. The TRDC init splits to two phases:
1. Early init phase will release TRDC from Sentinel and open write
permission to the memory where SPL image runs. Sentinel will set
the memory to RX only after ROM authentication for the OEM
closed part.
2. Init phase will configure TRDC to allow non-secure master to
access DDR. So the peripherals can work in u-boot.
