pci-epc-mem uses a page size equal to *PAGE_SIZE* (usually 4KB) to manage
the address space. However certain platforms like TI's K2G have a
restriction that this address space 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). Add support to handle
different page sizes here.

Introduce a new EP core layer in order to support endpoint functions in
linux kernel. This comprises the EPC library (Endpoint Controller Library)
and EPF library (Endpoint Function Library). EPC library implements
functions specific to an endpoint controller and EPF library implements
functions specific to an endpoint function.
