[PATCH v1 3/5] board: verdin-imx8mp: update lpddr4 configuration and training

[Marcel Ziswiler]

From: Emanuele Ghidoli <emanuele.ghidoli at toradex.com>

Update LPDDR4 configuration and training using updated spreadsheet and
tools from NXP using data from previous spreadsheet and verified
toward datasheet:
 - MX8M_Plus_LPDDR4_RPA_v9.xlsx
 - mscale_ddr_tool_v3.30.exe

From:
https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8M-Family-DDR-Tool-Release/ta-p/1104467

Some register values differ due to these fixes/modifications:

- corrected calculation of T_CKPDX parameter (equal to tCKCKEH for LPDDR4)
- corrected ECC related items, none of which affect normal operation
  when ECC is not enabled
- corrected formula for calculation of tRTP in cell D122
