    PCI: Remove redundant PCI_VSEC_HDR and PCI_VSEC_HDR_LEN_SHIFT

    Remove duplicate macro PCI_VSEC_HDR and its related macro
    PCI_VSEC_HDR_LEN_SHIFT from pci_regs.h to avoid redundancy and
    inconsistencies. Update VFIO PCI code to use PCI_VNDR_HEADER and
    PCI_VNDR_HEADER_LEN() for consistent naming and functionality.

    These changes aim to streamline header handling while minimizing impact,
    given the niche usage of these macros in userspace.
