Subject: media: venus: Fix NV12 decoder buffer discovery on HFI_VERSION_1XX
From: Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx>
commit 7f77fa9f378c528edb38dbf23ff1273c81429d49 upstream.
HFI_VERSION_1XX uses HFI_BUFFER_OUTPUT not HFI_BUFFER_OUTPUT2 for decoder
buffers.
venus_helper_check_format() places a constraint on an output buffer to be
of type HFI_BUFFER_OUTPUT2. HFI_1XX uses HFI_BUFFER_OUTPUT though.
Switching to the logic used in venus_helper_get_out_fmts() first checking
for HFI_BUFFER_OUTPUT and then HFI_BUFFER_OUTPUT2 resolves on HFI_1XX.

Validated playback with ffplay on db410c with h264 and vp8 decoding.
