Subject: [PATCH 2/2] media: verisilicon: Fix IMX8 native pixels format steps values

Hantro decoder non post-processed pixels formats steps are different
from post-processed ones.
Fix the steps according to hardware limitation.
Since reference frame pixels format issue has been fix, it is possible
to use V4L2_PIX_FMT_NV15_4L4 rather V4L2_PIX_FMT_P010_4L4 for 10bits
streams.

Fluster VP9 score goes up to 207/305.
HEVC score is still 141/147.
