PCI: Add managed pcim_request_region()
These existing functions:
pci_request_region()
pci_request_selected_regions()
pci_request_selected_regions_exclusive()
are "hybrid" functions built on __pci_request_region() and are managed if
pcim_enable_device() has been called, but unmanaged otherwise.
Add these new functions:
pcim_request_region()
pcim_request_region_exclusive()
These are *always* managed and use the new pcim_addr_devres tracking
infrastructure instead of find_pci_dr() and struct pci_devres.region_mask.
Implement the hybrid functions using the new "pure" functions and remove
struct pci_devres.region_mask, which is no longer needed.
