This patch adds support for the WQVGA LCD display used by
the KFR2R09 board. The LCD module is a TX07D34VM0AAA made
by Hitachi, and this module is made up by a R61517 chip
together with a 240x400 pixel display. The screen is
attached to the SuperH Mobile LCDC using a 18-bit SYS bus.

The register settings used by the SYS panel setup code are
based on an out-of-tree driver which apart from duplicating
all LCDC driver code and writing to non-existing hardware
registers also never was posted for upstream merge.

This cleans up the irqflags tracing code quite a bit and ties it
in to various missing callsites that caused an imbalance when
CONFIG_PROVE_LOCKING was enabled.

Previously this was catching on:

 987 #ifdef CONFIG_PROVE_LOCKING
 988     DEBUG_LOCKS_WARN_ON(!p->hardirqs_enabled);
 989     DEBUG_LOCKS_WARN_ON(!p->softirqs_enabled);
 990 #endif
 991     retval = -EAGAIN;

with hardirqs being doubly enabled, and subsequently bailing out
with the following call trace:

Convert the processor platform device setup
functions from __initcall() and sometimes
device_initcall() to arch_initcall().

This makes sure that the platform devices are
registered a bit earlier so the devices are
available when drivers register using initcall
levels earlier than device_initcall().

A good example is platform devices needed by
i2c-sh_mobile.c which registers a bit earlier
using subsys_initcall().

Convert the i2c-sh_mobile i2c bus driver to use
subsys_initcall() instead of module_init().

This change makes the driver register a bit earlier which
together with earlier platform data moves the time for probe().
The earlier probe() makes it possible to use i2c_get_adapter()
and i2c_transfer() from device_initcall().

The same strategy is used by other i2c bus drivers such as
i2c-pxa.c and i2c-s3c2410.c.

Convert the m66592-udc driver to use the on_chip flag
from platform data to enable on chip behaviour instead
of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness.

This makes the code cleaner and also allows us to support
both external and internal m66592 with the same kernel.

It also makes the Kconfig part more future proof since
we with this patch can add support for new processors
with on-chip m66592 without modifying the Kconfig.

The patch adds a m66592 header file for platform data
and ties in platform data to the existing m66592 devices.
