[PATCH v2] ARM: vexpress: Enable SPARSE_IRQ

[tixy@linaro.org (Jon Medhurst (Tixy))]

To enable vexpress to be included in multiplatform kernels containing
boards which require SPARSE_IRQ, we need to also support this option.
This turns out to be very simple...

We remove NR_IRQS from mach/irq.h as that is unused with SPARSE_IRQ
and include this header directly in ct-ca9x4.c as it will no longer
be included via asm/irq.h.
