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

Browse Source 
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.
