platform/x86: x86-android-tablets: Add LID switch support for Yoga Tablet 2 1050/830 series
The Yoga Tablet 2 1050/830 series have a HALL sensor for detecting
when their (optional) case/cover is closed over the screen.
Their Windows counterparts (alsmost the same HW, different BIOS)
model this as a LID switch. Add support for reporting this as
a LID switch on the Android models too.
