Subject: [PATCH] mb/google/volteer: Add non-ChromeOS TBMC support for 360/flip
 variants

The TBMC ACPI device is used by Windows ChromeEC drivers to determine
tablet mode and to enable motion sensors (accelerometer, gyroscope).
Since it's not needed/used by ChromeOS, restrict its inclusion to
non-ChromeOS builds.

TEST=build/boot Win11/Linux on eldrid, verify tablet mode and rotation
work properly, keyboard/touchpad disabled in tablet mode.
