Will Deacon	01e3b958ef	arch: Remove dummy mmiowb() definitions from arch code ... Now that no driver code is using mmiowb() directly, remove the dummy definitions remaining in architectures that don't make use of asm-generic/io.h, as well as the definition in asm-generic/io.h itself.

Will Deacon	420af15547	powerpc/mmiowb: Hook up mmwiob() implementation to asm-generic code ... In a bid to kill off explicit mmiowb() usage in driver code, hook up the asm-generic mmiowb() tracking code but provide a definition of arch_mmiowb_state() so that the tracking data can remain in the paca as it does at present This replaces the existing (flawed) implementation.
