pci: expand usage of pci_sbdf_t

Start by switching the seg, bus and devfn fields of pci_dev to a single
pci_sdbf_t field, and fixup the users. Also change the pci_conf and pci
capabilities related functions to use pci_sbdf_t as parameter instead of
passing the sbdf in multiple parameters. Finally also introduce a printf
format specifier to print a pci_sbdf_t.

IMO pci_sbdf_t it's nicer to use than passing around a sbdf in multiple
fields. However it's hard to expand the usage of pci_sbdf_t in the code
base without changing some of the core pci functions and the pci_dev
struct fields, hence this patch set.

Note there's still more low hanging fruit that could benefit from
switching to pci_sbdf_t, this patch series just changes some of the more
core pci functions to use pci_sbdf_t.

This series should not introduce any functional changes.

Roger Pau Monne (5):
  pci: use pci_sbdf_t in pci_dev
  pci: use function generation macros for pci_config_{write,read}<size>
  pci: switch pci_conf_{read/write} to use pci_sbdf_t
  print: introduce a format specifier for pci_sbdf_t
  pci: switch PCI capabilities related functions to use pci_sbdf_t
