The current implementation was rather tied to the packed_struct.h
definitions, which immediately began to clash when the packed_struct.h
types changed and drivers began to include packed_struct.h directly.

In order to support this sort of use it's necessary to get out of the way
with regards to namespace collisions, and at the same time we can also
kill off some duplicate code now that the unaligned headers are a bit
more broken out.

The master clock initialization for SH7201 was wholly bogus. Users of the
legacy API must initialize the clock rate through the struct clk itself
rather than returning the clock frequency. Given that the init function
itself is void, returning the frequency isn't terribly effective.

This follows the ARM change c0177800
("ARM: 6379/1: Assume new page cache pages have dirty D-cache") for the
same rationale:

    There are places in Linux where writes to newly allocated page
    cache pages happen without a subsequent call to flush_dcache_page()
    (several PIO drivers including USB HCD). This patch changes the
    meaning of PG_arch_1 to be PG_dcache_clean and always flush the
    D-cache for a newly mapped page in update_mmu_cache().

This addresses issues seen with executing binaries from MMC, in
addition to some of the other HCDs that don't explicitly do cache
management for their pipe-in buffers.

The perf hardware pmu got initialized at various points in the boot,
some before early_initcall() some after (notably arch_initcall).

The problem is that the NMI lockup detector is ran from early_initcall()
and expects the hardware pmu to be present.

Sanitize this by moving all architecture hardware pmu implementations to
initialize at early_initcall() and move the lockup detector to an explicit
initcall right after that.

GCC's __builtin_prefetch() was introduced a long time ago, all
supported GCC versions have it. So this patch is to use it for
implementing the prefetch on SH2A and SH4.

The current  prefetch implementation is almost equivalent with
__builtin_prefetch.
The third parameter in the __builtin_prefetch is the locality
that it's not supported on SH architectures.  It has been set
to three and it should be verified if it's suitable for SH2A
as well. I didn't test on this architecture.

The builtin usage should be more efficient that an __asm__
because less barriers, and because the compiler doesn't see the
inst as a "black box" allowing better code generation.

This has been already done on other architectures (see the commit:
0453fb3c).

Many thanks to Christian Bruel <christain.bruel@st.com> for his
support on evaluate the impact of the gcc built-in on SH4 arch.

This takes a bit of a sledgehammer to the machvec I/O routines. The
iomem case requires no special casing and so can just be dropped
outright. This only leaves the ioport casing for PCI and SuperIO
mangling. With the SuperIO case going through the standard ioport
mapping, it's possible to replace everything with generic routines.

now gets default-enabled for the vast majority of boards.
