Well, right now I have a slightly different view, because of the work on
the FIQ stuff.

We currently have the situation where the GIC on CT9x4 appears to be
different from other GICs, in that group 1 interrupts are never
delivered.  As the GIC is indistinguishable from working parts, this
currently squarely puts the Daniel's KGDB FIQ work, and work to use
FIQ for dumping backtraces in the case of a spinlock lockup beyond the
reach of the kernel right now, and nothing more than a local hack.

So, until we get to the bottom of this, I need Versatile Express support
to stay as-is, so there's no extraneous variables in the platform.  That
means right now I need the legacy stuff to stay as switching to DT will
add a huge variable into what's going on.
