Subject: [net 25/27] can: flexcan: add ECC initialization for LX2160A

From: Joakim Zhang <qiangqing.zhang@....com>

After double check with Layerscape CAN owner (Pankaj Bansal), confirm
that LX2160A indeed supports ECC feature, so correct the feature table.

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.
