Use the newly introduced __pci_epc_mem_init instead of pci_epc_mem_init to provide page_size to pci_epc_mem. This is in preparation for adding EP support to K2G which has a restriction that the address region should be either divided into 1MB/2MB/4MB or 8MB sizes (Ref: 11.14.4.9.1 Outbound Address Translation in K2G TRM SPRUHY8F January 2016 – Revised May 2017).
