Add dram support for the MT53E1G32D2FW-046 RevC part which is a single die
32Gbit density part vs RevA/B which were dual-die parts:
- use a previously unused EEPROM byte to denote a variant of the
base config to be patched
- add a dram description string
- return the board struct from eeprom_init and pass it to the
spl_dram_init function so that it has access to the EEPROM
- move ddr_init into the spl_dram_init so that it can be patched
in the per-soc init function

Move the determination of the dram timings into the soc-specific files.

The imx8mp venice boards can support 2000Mhz DRAM.
Update the DRAM config to support this.

The DRAM configuration for the 1GB and 4GB imx8mp venice boards had a
bus mapping issue (channel A and B swapped) which creates an invalid
deskewing configuration during training causing the DRAM to not be able
to run at its full bus speed.
Update the various config structures to resolve this.
