UBUNTU: SAUCE: drm/i915: Disable writing of TMDS_OE on Lenovo ThinkPad X1 series

BugLink: https://bugs.launchpad.net/bugs/1738523
There is a hw design on Lenovo ThinkPad X1 yoga/carbon:
Intel GEN9 display -> AlpineRidge -> PS8407 -> HDMI output

When switch mode on this HDMI output, it failed to writing on
I2C device 0x40/0x50. Then sometimes the HDMI output is disabled.

From Parade's support, tmds_oe is enabled by default, and keep it
enabled to fix this issue.

Add a workaround to bypass this TMDS_OE writing on identified
laptop models.
