6.14-stable review patch. If anyone has any objections, please let me know.

commit 035371c9e5098018b8512efc6a8812912469480c upstream.
The Wave5 521C variant does not support 10 bit decoding. When 10 bit decoding support was added for the 515 variant, a section of the code was removed which returned an error. This removal causes a timeout for the 521 variant, which was discovered during HEVC 10-bit decoding tests.
