It matches the latest what we call "Hardware Settings Reference" set
of values, and happens to be present in e.g. this tree:

https://github.com/sony-sdm845/android_kernel_sony_sdm845/blob/lineage-20/drivers/media/platform/msm/camera_v3/cam_sensor_module/cam_csiphy/include/cam_csiphy_1_0_hwreg.h

also worth noting, 845 is csiphy v1.0, not 1.1
