The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).
This also fixes !CONFIG_OF error:
  drivers/media/i2c/ov2640.c:1290:34: error: ‘ov2640_of_match’ defined but not used [-Werror=unused-const-variable=]
