drm/i915: fix gpio register detection logic for BIOS without VBT
commit 29874f44fbcbc24b231b42c9956f8f9de9407231 upstream.
if no VBT is present, crt_ddc_bus will be left at 0, and cause us
to use that for the GPIO register offset. That's never a valid register
offset, so let the "undefined" value be 0 instead of -1.
