MIPS: irq: Use DECLARE_BITMAP

Use the generic mechanism to declare a bitmap instead of unsigned long.

This could fix an overwrite defect of whatever follows irq_map.

Not all "#define NR_IRQS <value>" are a multiple of BITS_PER_LONG so
using DECLARE_BITMAP allocates the proper number of longs required
for the possible bits.

For instance:

arch/mips/include/asm/mach-ath79/irq.h:#define NR_IRQS                  51
arch/mips/include/asm/mach-db1x00/irq.h:#define NR_IRQS 152
arch/mips/include/asm/mach-lantiq/falcon/irq.h:#define NR_IRQS 328
