Bug Description

SRU justification:

[Impact]
When plugin HDMI cable, no HDMI output, kernel reported error:
[drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon
[drm:lspcon_resume [i915]] *ERROR* LSPCON init failed on port

[Fix]
Legacy LSPCON chip from MCA and Parade is only used for platforms,
Limit the support between GEN9 and GEN10.
The commit is already in 5.13, so only SRU for oem-5.10 and hirsute.

[Test]
Verified on hardware, HDMI output works fine.

[Where problems could occur]
The HDMI output may break.
