[PATCH 1/4] arm64: imx8mp: Fold inline ECC into spl.c on DH i.MX8MP DHCOM SoM

[Marek Vasut]

The inline ECC configuration is identical for 2 GiB DRAM variants
and 4 GiB DRAM variants of the SoM, no matter the rank count. Fold
the ECC configuration directly into spl.c to simplify the upcoming
deduplication. No functional change.
