Subject: [PATCH v2 1/6] media: renesas-ceu: Use of_device_get_match_data()

This driver can use the replacement API instead of calling
of_match_device() and then dereferencing the pointer that is returned.
This nicely avoids referencing the match table when it is undefined with
configurations where CONFIG_OF=n.
