PM / OPP: Remove ARCH_HAS_OPP

From: Mark Brown <broonie@linaro.org>

Since the OPP layer is a kernel library which has been converted to be
directly selectable by its callers rather than user selectable and
requiring architectures to enable it explicitly the ARCH_HAS_OPP symbol
has become redundant and can be removed. Do so.

Raphael, IIRC you said that you'd applied this but it seems not to have
appeared in -next.  There's a few more references crept in, I'll try to
get them removed at source.

I've queued this up for 3.17, thanks!
