All CPU-specific overloads are done at runtime now, so this common header
can go away and simply be folded back in to asm/ version.

This paves the way for allowing individual CPUs to overload the
individual flushing routines that they care about without having to
depend on weak aliases. SH-4 is converted over initially, as it wires
up pretty much everything. The majority of the other CPUs will simply use
the default no-op implementation with their own region flushers wired up.

We use flush_cache_page() outright in copy_to_user_page(), and nothing
else needs it, so just kill it off. SH-5 still defines its own version,
but that too will go away in the same fashion once it converts over.

All of the flush_dcache_mmap_lock()/flush_dcache_mmap_unlock()
definitions are identical across all CPUs, so just provide them
generically in asm/cacheflush.h.

This provides a central point for CPU cache initialization routines.
This replaces the antiquated p3_cache_init() method, which the vast
majority of CPUs never cared about.
