drm/i915/vlv_dsi: Add DMI quirk for backlight control issues on Lenovo Yoga Tab 3 (v2)
On the Lenovo Yoga Tab 3 Pro YT3-X90F there are 2 issues with the backlight
on/off MIPI sequences:
1. The backlight on sequence has an I2C MIPI sequence element which uses
bus 0, but there is a bogus I2cSerialBus resource under the GPU in
the DSDT which causes i2c_acpi_find_adapter() to pick the wrong bus.
2. There is no backlight off sequence, causing the backlight to stay on.
Add a DMI quirk fixing both issues.
v2:
- Add Closes tag to gitlab issue with drm.debug=0xe, VBT info
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9380
