platform/x86: alienware-wmi: Move Lighting Control State

Place Lighting Control State logic next to other attributes of the same
sysfs group.

While at it, rename:

store_control_state()	-> lighting_control_state_store()
show_control_state()	-> lighting_control_state_show()

Replace DEVICE_ATTR() with DEVICE_ATTR_RW() and do a general style
cleanup.
