PCI: Validate window resource type in pbus_select_window_for_type()

[ Upstream commit e5f72cb9cea599dc9f5a9b80a33560a1d06f01cc ]

After ebe091ad81e1 ("PCI: Use pbus_select_window_for_type() during IO
window sizing") and ae88d0b9c57f ("PCI: Use pbus_select_window_for_type()
during mem window sizing"), many bridge windows can't get resources
assigned:

  pci 0006:05:00.0: bridge window [??? 0x00001000-0x00001fff flags 0x20080000]: can't assign; no space
  pci 0006:05:00.0: bridge window [??? 0x00001000-0x00001fff flags 0x20080000]: failed to assign

Those commits replace find_bus_resource_of_type() with
pbus_select_window_for_type(), and the latter lacks resource type
validation.

Add the resource type validation back to pbus_select_window_for_type() to
match the original behavior.
