irqchip: mips-gic: Use proper iomem accessors
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.
