venice: lpddr4_timing_imx8mm: update ddr phy config for mscale_v3.10

Update the ddr phy config values to those created by the mscale_v3.10
tool. The original values were obtained using mscale_v3.10. The v3.10
tool removed ddr phy register values of 0x0.

This has no functional change but makes comparing and patching ddr
configuration easier in addition to slightly shrinking the DRAM config
size.
