Paul Mundt f9bd71f255 sh: Kill off unused cpu/cacheflush.h.
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.

Paul Mundt 37443ef3f0 sh: Migrate SH-4 cacheflush ops to function pointers.
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.

Paul Mundt 916e97834e sh: Kill off unused flush_icache_user_range().
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.

Paul Mundt 7fbb2d3bdd sh: consolidate flush_dcache_mmap_lock/unlock() definitions.
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.

Paul Mundt ecba106058 sh: Centralize the CPU cache initialization routines.
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.
