media: rkvdec: Remove of_match_ptr()

commit c2357dd9cbafc8ed37156e32c24884cfa8380b2f upstream.

When building with CONFIG_OF not set, the following clang
build warning is seen:

>> drivers/staging/media/rkvdec/rkvdec.c:967:34: warning: unused variable 'of_rkvdec_match' [-Wunused-const-variable]

Fix the warning by removing the unnecessary of_match_ptr().
