Clean and invalidate the full data cache as the armv6_start.S code assumes
that the caches are disabled on entry which armv7_exec_kernel ensures.
When caches are disabled armv6_start.S will invalidate (not clean) the
cache and this can lose u-boot data for the u-boots that now don't
perform their own cache maintenance.

An example of such a u-boot is the banana pro that chuq@ has tried which

Improving things so that the architected caches could remain on would be
better, but that's a much bigger change / set of changes.

Allow an MD check in prepare_boot and use it on arm64 (aarch64) to check
that, if a big endian kernel is seen, the CPU is capable of supporting BE
data accesses at EL0 via ID_AA64MMFR0_EL1.BigEnd.

Sync w/ HEAD.

Add a hook for MD specific info to print in the "ver" command. Use this
to print the value of the current execution level in bootaa64.
