[PATCH v3 4/6] PCI: Remove request_flags relict from devres

[Philipp Stanner <phasta@xxxxxxxxxx>]

pcim_request_region_exclusive(), the only user in PCI devres that needed
exclusive region requests, has been removed.

All features related to exclusive requests can, therefore, be removed,
too. Remove them.
