ACPI: bus: Indicate support for the Generic Event Device thru _OSC
A device driver for the Generic Event Device (ACPI0013) already
exists for quite some time, but support for it was never reported
thru _OSC.
Fix this by setting bit 11 ("Generic Event Device support") when
evaluating _OSC.
Fixes: 3db80c230da1 ("ACPI: implement Generic Event Device")
