platform/surface: aggregator_tabletsw: Add support for book mode in POS subsystem
Devices with a type-cover have an additional "book" mode, deactivating
type-cover input and turning off its backlight. This is currently
unsupported, leading to the warning
surface_aggregator_tablet_mode_switch 01:26:01:00:01: unknown device posture for type-cover: 6
Therefore, add support for this state and map it to enable tablet-mode.
