media: verisilicon: Fix IMX8 native pixel-format step values

The Hantro decoder non post-processed pixel-format steps are different
from the post-processed ones. Fix the steps according to the hardware
limitations. Since reference frame pixel-format issues have been fixed,
it is possible to use V4L2_PIX_FMT_NV15_4L4 rather V4L2_PIX_FMT_P010_4L4
for 10bit streams.

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