[PATCH 1/2] MdePkg/PciSegmentInfoLib: Add missing EFIAPI to GetPciSegmentInfo()

["Ni, Ray" <ray.ni@intel.com>]

All public APIs should have EFIAPI modifier. Somehow PciSegmentInfoLib
missed the EFIAPI modifier.
The patch updates the library header file and NULL instance in MdePkg
to add the missing EFIAPI.
