gpu: nova-core: do not consider 0xBB77 as a valid PCI ROM header signature

Nvidia GPUs have some PCI expansion ROM sections that have an Nvidia-
specific signature instead of 0xAA55.  Signature 0xBB77 is actually an
internal-only value that has been deprecated for over a decade.
Nova-core will never encounter a GPU with that signature, so don't look
for it.
