[PATCH] at91: fix compile breakage with VMALLOC_END

[Jamie Iles]

From: Jamie Iles <jamie at jamieiles.com>

VMALLOC_END is defined in terms of AT91_VIRT_BASE but this needs
mach/hardware.h for it's definition.

In file included from arch/arm/mach-at91/board-usb-a926x.c:26:0:
include/linux/mm.h: In function 'is_vmalloc_addr':
include/linux/mm.h:305:41: error: 'AT91_VIRT_BASE' undeclared (first use in this function)
include/linux/mm.h:305:41: note: each undeclared identifier is reported only once for each function it appears in

This is a bit more heavyweight than most of the other platforms,
but it's the simplest fix.
