PCI: Remove unused pci_vpd_truncate()
My philosophy is unused code is dead code. And dead code is subject to bit
rot and is a likely source of bugs. Use it or lose it.
This reverts db5679437a
("PCI: add interface to set visible size of
VPD"), removing this interface:
pci_vpd_truncate()
[bhelgaas: split to separate patch, also remove prototype from pci.h]
