Add initial support of camera sensors on Valve "Steam Frame" device.

The change enables CAMSS and adds description of
- a pair of OmniVision OV6211 monochrome eyetracking camera sensors,
- a pair of OmniVision OG01A1B monochrome front camera sensors.

There is another pair of OmniVision OG0VE10 camera sensors found on
the device, its description requires a combo mode feature support in
the SM8650 CAMSS CSIPHY driver.

Changes from v1 to v2:
* added Abel's Reviewed-by tag, thanks for review of the change,
* split default/sleep pinctl controls (reported by Sashiko bot),
* fixed data-lanes value of OG01A1B endpoints (reported by Sashiko bot),

OTOH the reported out-of-range '<&pm8550vs_e_gpios 6 ...>' value is
a false positive error by the bot, the controller gets GPIO numbers
from 1 to 6 range.
