PCI: Remove redundant set of request functions

PCI: Remove redundant set of request functions

When the demangling of the hybrid devres functions within PCI was
implemented, it was necessary to implement several PCI functions a
second time to avoid cyclic calls, since the hybrid functions in pci.c
call the managed functions in devres.c, which in turn can be directly
used outside of PCI and needed request infrastructure, too.

Therefore, __pcim_request_region_range(), __pci_release_region_range()
and wrappers around them were implemented.

The hybrid nature has recently been removed from all functions in pci.c.
Therefore, the functions in devres.c can now directly use their
counterparts in pci.c without causing a call-cycle.

Remove __pcim_request_region_range(), __pcim_request_region_range() and
the wrappers. Use the corresponding request functions from pci.c in
devres.c
