[PATCH] board: vexpress_ca9x4: Enable D-cache and MMU

[Josef Holzmayr]

Thanks Mark and Tom!

Just so I understand it correctly, this patch means that after the next
u-boot release we can continue to use the  vexpress-ca9 emulation as long
as we also make sure QEMU is current? If so, do you happen to know which
minimum version would apply?
