fsl_pci_ep: add VF ATMU access support
All VFs of a PF share the common inbound/outbound windows
except translation registers of outbound windows. A VF can
only change translation registers of outbound windows. A PF
can change all ATMU of VF.
The patch provides VF ATMU register definition and provides
interfaces to access inbound/outbound windows. It also adds
PCI_EP_REGION_MEM type to return PF's memory resource. The
application can get and reassign the memory resource to VF.
