Some of the H265 status flags are wrong. Redefine them to corespond to
Allwinner CedarC open source userspace library. Only one of these flags
is actually used and new value also matches value used in libvdpau-sunxi
library, which is proven to be working.
Note that wrong (old) value in right circumstances (in combination with
another H265 decoding bug) causes driver lock up. With this fix decoding
is still broken (green output) but at least driver doesn't lock up.

This is the sample which locks up driver:

Second bug is actually in HEVC API - dependent slice flag for slice is
missing. Similar flag in PPS exists, but that only tells if this
feature is enabled and should not be used for slice.
This will be fixed later.
