drm/amd/display: Use ARRAY_SIZE for array length
Use of macro ARRAY_SIZE to calculate array size minimizes
the redundant code and improves code reusability.
./drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c:164:45-46: WARNING: Use ARRAY_SIZE.
./drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c:183:47-48: WARNING: Use ARRAY_SIZE.
./drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c:237:45-46: WARNING: Use ARRAY_SIZE.
./drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c:257:47-48: WARNING: Use ARRAY_SIZE.
