irqchip: mips-gic: Move gic_get_c0_*_int() to asm/mips-gic.h

The linux/irqchip/mips-gic.h header is now almost empty. Move the
declarations of gic_get_c0_compare_int(), gic_get_c0_perfcount_int() &
gic_get_c0_fdc_int() to asm/mips-gic.h in order to close in on being
able to delete the former header.
