google/chromeec: Add support for "base attached switch" device
On some detachables, the mere presence of attached base is not enough to
determine whether the device is in tablet mode or not, so we introducing
a new "switch" in EC, separate from "Tablet Mode" switch, to signal
whether the base is attached or not.
We also want the driver to be separate from cros_ec_keyb, so we create
a new ACPI device, C(hrome)B(ase)A(ttached)S(witch), with HID GOOG000B,
and guard it with EC_ENABLE_CBAS_DEVICE.
