This patch moves the GIC interface to a separate base class and makes all interrupt devices use that base class instead of a pointer to the PL390 implementation. This allows us to have multiple GIC implementations. Future implementations will allow in-kernel GIC implementations when using hardware virtualization. --HG-- rename : src/dev/arm/gic.cc => src/dev/arm/gic_pl390.cc rename : src/dev/arm/gic.hh => src/dev/arm/gic_pl390.hh
