drivers/ddr/fsl: Update DDR driver for DDR4
Add/update registers for DDR4, including DQ mappings. Allow raw timing
method used for all controllers. Update mode_9 register to 0x500 for
improved stability. Check DDR controller version number individually
in case a SoC has multiple DDR controllers of different versions.
Increase read-write turnaround for DDR4 high speeds.
