[v2,00/23] QUICC Engine support on ARM

Message

There have been several attempts in the past few years to allow
building the QUICC engine drivers for platforms other than PPC. This
is yet another attempt.

In v2, I've fixed a few style issues. But more importantly, it now
contains enough to actually remove the PPC32 dependency from
CONFIG_QUICC_ENGINE, so that's what the last patch does.

I haven't found a way to address Christophe's concern over the
performance impact of using the (on powerpc) out-of-line iowrite32be
instead of out_be32. I could of course introduce some qe_ prefixed
helpers (similar to the already added qe_clrsetbits ones) and make
their definition dependent on PPC32 or not, but that seems to be a bit
ugly.
