[PATCH v3 1/1] eal: add internal function to get base address

[Srikanth Yalavarthi]

Added an internal helper to get OS-specific EAL mapping base address

This helper can be used by the drivers to map host address range with
offload devices and would be need for device specific operations like
firmware load
