fsl_pci_ep: initialize PF and VF ATMU
The first PCI controller of T4 has two physical functions(PF).
Each physical functions supports 64 virtual functions(VF).
There may be multiple functions to share PCI memory resource.
The patch first disables all the inbound/outbound windows then,
divides the PCI memory resource equally among all functions
and enable a PF/VF outbound window to cover assigned memory.
