Subject: media: venus: Fix NV12 decoder buffer discovery on HFI_VERSION_1XX
Author:  Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx>
Date:    Tue Jul 26 04:14:55 2022 +0200

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.

db410c before:
root@linaro-alip:~# v4l2-ctl  -d /dev/video0 --list-formats
ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture Multiplanar

        [0]: 'MPG4' (MPEG-4 Part 2 ES, compressed)
        [1]: 'H263' (H.263, compressed)
        [2]: 'H264' (H.264, compressed)
        [3]: 'VP80' (VP8, compressed)

root@linaro-alip:~# v4l2-ctl  -d /dev/video1 --list-formats
ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture Multiplanar

db410c after:
root@linaro-alip:~# v4l2-ctl  -d /dev/video0 --list-formats
ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture Multiplanar

        [0]: 'MPG4' (MPEG-4 Part 2 ES, compressed)
        [1]: 'H263' (H.263, compressed)
        [2]: 'H264' (H.264, compressed)
        [3]: 'VP80' (VP8, compressed)

root@linaro-alip:~# v4l2-ctl  -d /dev/video1 --list-formats
ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture Multiplanar

        [0]: 'NV12' (Y/CbCr 4:2:0)

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