QCS8300 provides
- 2 x VFE, 3 RDI per VFE
- 5 x VFE Lite, 6 RDI per VFE
- 2 x CSID
- 5 x CSID Lite
- 3 x TPG
- 3 x CSIPHY

We have tested this on qcs8300-ride board with 'Test Pattern Generator'
TPG driver support will be posted in a follow up series.

Tested with following commands:
- media-ctl -d /dev/media0 --reset
- yavta --no-query -w '0x009f0903 0' /dev/v4l-subdev0
- media-ctl -d /dev/media0 -V '"msm_tpg0":0[fmt:SRGGB10/1920x1080
  field:none]'
- media-ctl -d /dev/media0 -V '"msm_csid0":0[fmt:SRGGB10/1920x1080
  field:none]'
- media-ctl -d /dev/media0 -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/1920x1080
  field:none]'
- media-ctl -d /dev/media0 -l '"msm_tpg0":1->"msm_csid0":0[1]'
- media-ctl -d /dev/media0 -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta --no-query -w '0x009f0903 9' /dev/v4l-subdev0
- yavta -B capture-mplane -n 5 -f SRGGB10P -s 1920x1080 /dev/video0
  --capture=7

Used following tools for the sanity check of these changes.

- make -j32 W=1
- ./scripts/checkpatch.pl
