board: vexpress_ca9x4: Enable D-cache and MMU

Enable the D-cache, which will also enable the MMU.  The latter
make sure we don't do unaligned access on Strongly-ordered memory,
which has UNPREDICTABLE behaviour according the architecture
definition.  This fixes using U-Boot with recent versions of
QEMU's vexpress-ca9 emulation.
