immediately after re-boot or during a jump in to a secondary kernel.

Add USB gadget support for port CN26 on the Solution Engine 7724
board. The r8a66597-udc driver is hooked up as a platform device
and some registers are configured to enable the USB in gadget mode.
The hardware driving the USB port is the on-chip USB1 block in
the sh7724 processor configured as USB gadget controller.

Add USB gadget support for port YC301 on the KFR2R09 board.
The r8a66597-udc driver is hooked up as a platform device,
clocks are enabled via I2C and some registers are configured
to enable the USB in gadget mode. The hardware driving the
USB port is the on-chip USB0 block in the sh7724 processor
configured as USB gadget controller.
This board is using external hardware to detect USB hotplug
events and allows the processor to dynamically start and stop
clocks. This well thought out hardware feature is unused at
this point and plug and play is unfortunately unsupported.
To properly support all hardware features the USB gadget
stack may need some adjustment.

This patch updates the Solution Engine 7724 board code to use
in-SoC KEYSC resources for the keyboard platform device. Using
the in-SoC key scan controller fixes a crash-during-resume issue.
Without this patch the KEYSC hardware block located in the board
specific FPGA is used together with an external IRQ which is
routed through the FPGA and handled by some board specific demux
code. This board specific FPGA interrupt code does not implement
desc->set_wake() so the enable_irq_wake() call in the sh_keysc
driver will fail at suspend-to-ram time and the disable_irq_wake()
will bomb out when resuming.
Changing the platform data to use the in-SoC KEYSC hardware makes
the se7724 board support code less special which is a good thing.
Also, the board specific KEYSC pin setup code selects in-SoC pin
functions already which makes the current FPGA platform device data
look like a typo.

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.

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.
