ArmPkg: Renamed library 'PL390GicLib' into 'ArmGicLib'
This library is the interface for the ARM Generic Interrupt Controller Architecture Specification. ARM Platform can use any GIC controller (not necessary PL390 GIC). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12411 6f19259b-4bc3-4df7-8a09-765794883524
