ec/google/chromeec: move TBMC ACPI device under CREC
Tablet motion control is a function of the EC, and under Windows, the
TBMC device needs to be initialized after CREC, or driver init will
fail. The only way to ensure this happens is for TBMC to be a child
device under CREC.
TEST=build/boot Win11, Linux on google/eve, verify tablet mode drivers
loaded and orientation switching functional under both OSes.
