can: flexcan: rename feature into quirks
This patch renames the "features" member of struct flexcan_devtype_data to
"quirks". The corresponding defines are renamed too, to reflect what they
actually do.
FLEXCAN_HAS_V10_FEATURES -> FLEXCAN_QUIRK_DISABLE_RXFG
FLEXCAN_HAS_BROKEN_ERR_STATE -> FLEXCAN_QUIRK_BROKEN_ERR_STATE
FLEXCAN_HAS_MECR_FEATURES -> FLEXCAN_QUIRK_DISABLE_MECR
