net: can: Use device_get_match_data()

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Error checking for matching and match data was not necessary as matching
is always successful if we're already in probe and the match tables always
have data pointers.
