Pull chrome platform updates from Benson Leung:
"cros-ec:
- Error code cleanup across cros-ec by Guenter
- Remove cros_ec_cmd_xfer in favor of cros_ec_cmd_xfer_status
cros_ec_typec:
- Landed initial USB4 support in typec connector class driver for
cros_ec
- Role switch bugfix on disconnect, and reordering configuration
steps
cros_ec_lightbar:
- Fix buffer outsize and result for get_lightbar_version
misc:
- Remove config MFD_CROS_EC, now that transition from MFD is complete
- Enable KEY_LEFTMETA in new location on arm based cros-ec-keyboard
keymap"
