[PATCH 7/8] PCI: dwc: Remove surplus and document missing function parameters

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

Add missing documentation for the parameters "ks_pcie", "bus"
and "pci" of the ks_pcie_set_dbi_mode(), ks_pcie_clear_dbi_mode(),
ks_pcie_v3_65_add_bus() and ks_pcie_link_up() functions and resolve
build time warnings related to kernel-doc:

  drivers/pci/controller/dwc/pci-keystone.c:356: warning: Function
  parameter or member 'ks_pcie' not described in 'ks_pcie_set_dbi_mode'

  drivers/pci/controller/dwc/pci-keystone.c:375: warning: Function
  parameter or member 'ks_pcie' not described in
  'ks_pcie_clear_dbi_mode'

  drivers/pci/controller/dwc/pci-keystone.c:456: warning: Function
  parameter or member 'bus' not described in 'ks_pcie_v3_65_add_bus'

  drivers/pci/controller/dwc/pci-keystone.c:493: warning: Function
  parameter or member 'pci' not described in 'ks_pcie_link_up'

  drivers/pci/controller/dwc/pci-keystone.c:615: warning: Excess
  function parameter 'irq' description in 'ks_pcie_legacy_irq_handler'

No change to functionality intended.
