media: sti: c8sectpfe: drop of_match_ptr() to avoid unused variables

When CONFIG_OF is not set, "of_match_ptr(<match_table>)" compiles to NULL,
which leaves <match_table> unused, leading to warning such as:

drivers/media/platform/st/sti/c8sectpfe/c8sectpfe-core.c:1175:34:
warning: unused variable 'c8sectpfe_match' [-Wunused-const-variable]

Drop the of_match_ptr usage to avoid such warning.
