Andrey Konovalov 612edd4888 media: qcom: camss: Fix csid-gen2 for test pattern generator 
[ Upstream commit 87889f1b7ea40d2544b49c62092e6ef2792dced7 ]

In the current driver csid Test Pattern Generator (TPG) doesn't work.
This change:
- fixes writing frame width and height values into CSID_TPG_DT_n_CFG_0
- fixes the shift by one between test_pattern control value and the
  actual pattern.
- drops fixed VC of 0x0a which testing showed prohibited some test
  patterns in the CSID to produce output.
So that TPG starts working, but with the below limitations:
- only test_pattern=9 works as it should
- test_pattern=8 and test_pattern=7 produce black frame (all zeroes)
- the rest of test_pattern's don't work (yavta doesn't get the data)
- regardless of the CFA pattern set by 'media-ctl -V' the actual pixel
  order is always the same (RGGB for any RAW8 or RAW10P format in
  4608x2592 resolution).

Tested with:

RAW10P format, VC0:
 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_csid0":1->"msm_vfe0_rdi0":0[1]'
 v4l2-ctl -d /dev/v4l-subdev6 -c test_pattern=9
 yavta -B capture-mplane --capture=3 -n 3 -f SRGGB10P -s 4608x2592 /dev/video0

RAW10P format, VC1:
 media-ctl -V '"msm_csid0":2[fmt:SRGGB10/4608x2592 field:none]'
 media-ctl -V '"msm_vfe0_rdi1":0[fmt:SRGGB10/4608x2592 field:none]'
 media-ctl -l '"msm_csid0":2->"msm_vfe0_rdi1":0[1]'
 v4l2-ctl -d /dev/v4l-subdev6 -c test_pattern=9
 yavta -B capture-mplane --capture=3 -n 3 -f SRGGB10P -s 4608x2592 /dev/video1

RAW8 format, VC0:
 media-ctl --reset
 media-ctl -V '"msm_csid0":0[fmt:SRGGB8/4608x2592 field:none]'
 media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB8/4608x2592 field:none]'
 media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
 yavta -B capture-mplane --capture=3 -n 3 -f SRGGB8 -s 4608x2592 /dev/video0
