radeon/vcn : Corrected dpb_size calculation for VP9_2
Currently dpb_size for VP9 profile0 and profile2 is same eventhough for profile2 dpb_size is multiplied by extra 3/2 and we are seeing VM_L2_PROTECTION_FAULT error and ring vcn_dec timeout because of less dpb_size for VP9_2.
This patch will correct dpb_size for VP9_2 and fixes the issue. CC: mesa-stable Signed-off-by: SureshGuttula suresh.guttula@amd.com
