[PATCH] platform/x86/amd: pmc: Add Lenovo Yoga 6 13ALC6 to pmc quirk list

[Mario Limonciello]

From: Mario Limonciello <mario.limonciello@amd.com>

The Lenovo Yoga 6 13ACL6 82ND has a similar BIOS problem as other Lenovo
laptops from that vintage that causes a rather long resume from suspend.

Add it to the quirk list that manipulates the scratch register to avoid
the issue.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.
