ARM: ux500: Enable HIGHMEM in the u8500 defconfig
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.
