Revert "coreboot: rev 8b52167a9f 13 July 2025, rebase t480"HEADmaster

This reverts commit 32dfdfbb01b84bb9c058e9b84305f15a14d4e231.

The update caused an issue on T480:

Backlight comes on, then off, then on, then off, repeatedly, and
never gets to the payload. Will have to investigate further.

-Subject: [PATCH 39/43] ec/lenovo/h8: Rework invalid temperature reporting
-
-As far back as the x201, Lenovo's EC ACPI has treated 128 as an invalid
-value, and returned a corrected value when it is reported/read from EC
-RAM. Drop the ME workaround, which most H8-equipped boards select, in
-favor of Lenovo's logic, since both accomplish the same result.
