Get rid of the ugly GICREAD/GICWRITE/GICBIS macros and use proper
iomem accessors instead. Since the GIC registers are not directly
accessed outside of the GIC driver any more, make gic_base static
and move all the GIC register manipulation macros out of gic.h,
converting them to static inline functions.
