From: D M Sharath Kumar <sharath.kumar.d.m@intel.com>

added new callback for
1) read,write to root port configuration registers
2) read,write to endpoint configuration registers
3) root port interrupt handler

agilex and newer platforms need to implemant the callback
and generic root port driver should work ( without much changes )
, legacy platforms (arria and startix) implement configuration read,write
directly in wrapper api _altera_pcie_cfg_read/_altera_pcie_cfg_write
