Subject: hw/arm_gic.c: Define .class_size in arm_gic_info TypeInfo

Add the missing .class_size definition to the arm_gic_info TypeInfo.
This fixes the memory corruption and possible segfault that otherwise
results when the class struct is allocated at too small a size and
the class init function writes off the end of it.
