rambi: Add _PRW for LID0 ACPI Device
The kernel will not track wakeup events for devices unless they have
a defined _PRW. There is no EC output of the lid signal coming to
a GPIO and instead it pulses PCH_WAKE#.
BUG=chrome-os-partner:27631
TEST=Manual on Rambi.
- Run lidclose + lidopen on EC console, verify that wakeup_count
increments.
- Run lidclose + lidopen in rapid succession, verify that suspend
request is aborted.
BRANCH=Rambi.
