Subject: [PATCH 5.17 0171/1126] media: venus: venc: Fix h264 8x8 transform control

From: Stanimir Varbanov <stanimir.varbanov@...aro.org>

commit 61b3317dd424a3488b6754d7ff8301944d9d17d7 upstream.

During encoder driver open controls are initialized via a call
to v4l2_ctrl_handler_setup which returns EINVAL error for
V4L2_CID_MPEG_VIDEO_H264_8X8_TRANSFORM v4l2 control. The control
default value is disabled and because of firmware limitations
8x8 transform cannot be disabled for the supported HIGH and
CONSTRAINED_HIGH profiles.

To fix the issue change the control default value to enabled
(this is fine because the firmware enables 8x8 transform for
high and constrained_high profiles by default). Also, correct
the checking of profile ids in s_ctrl from hfi to v4l2 ids.
