platform/surface: aggregator_tabletsw: Add support for book mode in KIP subsystem
[ Upstream commit 9bed667033e66083d363a11e9414ad401ecc242c ]
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 01:0e:01:00:01: unknown KIP cover state: 6
Therefore, add support for this state and map it to enable tablet-mode.
Fixes: 9f794056db5b ("platform/surface: Add KIP/POS tablet-mode switch driver")
