can: rcar_canfd: Add suspend/resume support
On R-Car Gen3 using PSCI, s2ram powers down the SoC. After resume, the
CAN-FD interface no longer works. Trying to bring it up again fails:
# ip link set can0 up
RTNETLINK answers: Connection timed out
# dmesg
...
channel 0 communication state failed
Fix this by populating the (currently empty) suspend and resume
callbacks, to stop/start the individual CAN-FD channels, and
(de)initialize the CAN-FD controller.
