[PATCH 3/4] platform/x86: intel-vbtn: support KEY_ROTATE_DISPLAY

[Stefan BrÃns]

The Rotate Lock button event is emitted on the XPS 12 (BIOS A8, but not
on BIOS A2).

Signed-off-by: Stefan BrÃns <stefan.bruens@xxxxxxxxxxxxxx>

The changes where tested on an XPS 12 with BIOS version A8 (2015-03-03).
An earlier BIOS version (A2, ~2013) did not report the event, at least
not using the INT33D6 plattform device.
