PM / OPP: Remove ARCH_HAS_OPP

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.

-Architectures that provide a SoC framework for OPP should select ARCH_HAS_OPP
-to make the OPP layer available.

 OPP layer expects each domain to be represented by a unique device pointer. SoC
 framework registers a set of initial OPPs per device with the OPP layer. This
 list is expected to be an optimally small number typically around 5 per device.
