lippert/frontronner-af & toucan-af: Fix IASL warnings

Not all the paths through the _OSC method returned a value.  According
to the ACPI spec (5.0 & 6.0), bit 2 needs to be set for an unrecognized
GUID.

Fixes warnings for both platforms:
dsdt.aml 1143:  Method(_OSC,4)
Warning  3115 -          ^ Not all control paths return a value (_OSC)
dsdt.aml 1143:  Method(_OSC,4)
Warning  3107 -          ^ Reserved method must return a value
(Buffer required for _OSC)
