Changes in v4:
- Merged device tree changes and driver changes in one series
- Remove obsolete comment about rev2 functional RX FIFO.
Changes in v3:
- Add LS1021 in FLEXCAN hardware feature flags table
- Kept LS1021 compatible in one line, even if it's more than 80
chars.
- Add PERR_STATE quirk and USE_OFF_TIMESTAMP quirk and
ENABLE_EACEN_RRS quirk for LS1021A.
- Tested on LS1021A using "cangen can0 -D 11223344DEADBEEF -L 8 -R"
and "cangen can0 -D 11223344DEADBEEF -L 8"
Changes in v2:
- No change.
