PCI: endpoint: Pass page size as argument to pci_epc_mem_init()

pci_epc_mem_init() internally used page size equal to *PAGE_SIZE* to manage the address space so instead just pass the page size as a argument to pci_epc_mem_init(). Also make pci_epc_mem_init() as a C function instead of a macro function in preparation for adding support for pci-epc-mem core to handle multiple windows.
