[PATCH] PCI: cadence: Remove surplus and document missing struct members

["Krzysztof Wilczyński" <kw@linux.com>]

Add missing documentation for the members "dev", "phy_count", "phy" and
"link" of the struct cdns_pcie, and remove surplus member "bus".

Thus resolve build time warnings related to kernel-doc:

  drivers/pci/controller/cadence/pcie-cadence.h:281: warning: Function parameter or member 'dev' not described in 'cdns_pcie'
  drivers/pci/controller/cadence/pcie-cadence.h:281: warning: Function parameter or member 'phy_count' not described in 'cdns_pcie'
  drivers/pci/controller/cadence/pcie-cadence.h:281: warning: Function parameter or member 'phy' not described in 'cdns_pcie'
  drivers/pci/controller/cadence/pcie-cadence.h:281: warning: Function parameter or member 'link' not described in 'cdns_pcie'

No change to functionality intended.
