This series adds driver changes to bring up the TPG interfaces
in LeMans, Monaco, Hamoa.

We have tested this on LeMans EVK board and qcs8300-ride board and
Hamoa EVK board with 'Test Pattern Generator'.
Unlike CSID TPG, this TPG can be seen as a combination of CSIPHY
and sensor.

Tested with following commands:
- media-ctl --reset
- media-ctl -V '"msm_tpg0":0[fmt:SRGGB10/4608x2592 field:none]'
- media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4608x2592 field:none]'
- media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4608x2592 field:none]'
- media-ctl -l '"msm_tpg0":1->"msm_csid0":0[1]'
- media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- v4l2-ctl -d /dev/v4l-subdev1 -c test_pattern=9
- yavta -B capture-mplane -n 5 -f SRGGB10P -s 4608x2592 /dev/video2
  --capture=7
