phy: phy-can-transceiver: Check driver match and driver data against NULL
Every platform driver can be forced to match a device that doesn't
match its list of device IDs because of device_match_driver_override()
so platform drivers that rely on the existence of a device's driver
data need to verify its presence.
Accordingly, add requisite match and driver data checks against NULL
to the driver where they are missing.
