Marc Gonzalez 9ff328de02 clk: qcom: mmcc-msm8998: fix venus clock issue 
[ Upstream commit e20ae5ae9f0c843aded4f06f3d1cab7384789e92 ]

Right now, msm8998 video decoder (venus) is non-functional:

$ time mpv --hwdec=v4l2m2m-copy --vd-lavc-software-fallback=no --vo=null --no-audio --untimed --length=30 --quiet demo-480.webm
 (+) Video --vid=1 (*) (vp9 854x480 29.970fps)
     Audio --aid=1 --alang=eng (*) (opus 2ch 48000Hz)
[ffmpeg/video] vp9_v4l2m2m: output VIDIOC_REQBUFS failed: Connection timed out
[ffmpeg/video] vp9_v4l2m2m: no v4l2 output context's buffers
[ffmpeg/video] vp9_v4l2m2m: can't configure decoder
Could not open codec.
Software decoding fallback is disabled.

Bryan O'Donoghue suggested the proper fix:
- Set required register offsets in venus GDSC structs.
- Set HW_CTRL flag.

$ time mpv --hwdec=v4l2m2m-copy --vd-lavc-software-fallback=no --vo=null --no-audio --untimed --length=30 --quiet demo-480.webm
 (+) Video --vid=1 (*) (vp9 854x480 29.970fps)
     Audio --aid=1 --alang=eng (*) (opus 2ch 48000Hz)
[ffmpeg/video] vp9_v4l2m2m: VIDIOC_G_FMT ioctl
[ffmpeg/video] vp9_v4l2m2m: VIDIOC_G_FMT ioctl
...
Using hardware decoding (v4l2m2m-copy).
