After double check with Layerscape CAN owner (Pankaj Bansal), confirm
that LS1021A doesn't support ECC, and LX2160A indeed supports ECC.
For SoCs with ECC supported, even use FLEXCAN_QUIRK_DISABLE_MECR quirk to
disable non-correctable errors interrupt and freeze mode, had better use
FLEXCAN_QUIRK_SUPPORT_ECC quirk to initialize all memory.
