pci: Remove unused pci_get_*_by_mask() functions

The helper functions pci_get_{byte,word,long,quad}_by_mask()
were added in 2012 in commit c9f50cea70a1596. In the decade
since we have never added a single use of them.

The helpers clearly aren't that helpful, so drop them
rather than carrying around dead code.
