drm/i915/bios: Remove version number comment from DEVICE_HANDLE_EFP4
DEVICE_HANDLE_EFP4 has actually been in use since the very beginning,
or at least something has been occupying that bit because old
VBTs actually use it, and it definitely looks to be about external
displays given how its used. So let's ignore what the current spec
claims and remove the misleading version number comment.
