[PATCH] ARM: ux500: Enable HIGHMEM in the u8540 defconfig

[Lee Jones]

In order to utilise all of the memory located on ux500 based devices
we have to enable HIGHMEM. Without it the kernel truncates memory down
to what's left after the PAGE_OFFSET has been applied, which doesn't
leave an awful lot, especially if we're running large rootfs' such
as full Linux desktop distributions or Android.
