Add mram-ecc-cfg property which indicates the error correction code config
and enable the same for FSD platform.

In FSD, error correction code (ECC) is configured via PERIC SYSREG
registers.

For net-folks: although the DTS patches are here as well, but they must
go via ARM SOC tree, so pick only network/can drivers and bindings when
they are ready.

Best regards,
