This patch unifies the sh3 external irq pin code. It buys us some
savings with reduced code redundancy, but the main feature with
this change is irq sense selection support for all sh3 processors.

This header is needed on other architectures as well (namely h8300),
which currently fails to build without this in place. Rather than
duplicating the port definition completely there, just move this to a
common location instead.
This should get h8300 working again for 2.6.25, in addition to the
changes already pushed by Sato-san in -rc2.

Fix the RTC resources setup for sh770x. Whit these proper
start values RTC driver (drivers/rtc/rtc-sh.c) works.

This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.
The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

With the intc core improved it is now possible to put the intc data
structures in the initdata section.
Version two of this patch puts the __initdata inside DECLARE_INTC_DESC()
and removes the __initdata included in the board specific r2d code.

We need a secondary register member in struct intc_prio_reg to support
dual priority registers used by ipi on x3.

This patch removes redundant interrupt code for the shmin board which
is using a sh770x processor and 4 IRQ lines as individual interrupts
(IRQ-mode).

The intc tables for sh3 currently contain a typo where the bit
fields in IPRD are mixed up for IRQ4 and IRQ5. This patch makes
sure the correct bit fields are used - all according to the
datasheets.

This patch adds a few missing vectors for sh7707. The only interrupt
controller differences between sh7707 and sh7709 seem to be added
vectors for one LCD controller and two PCMCIA slots.

This patch unifies the cpu specific interrupt setup code for
sh7706, sh7707, sh7708 and sh7709 and moves the code into a new
file called setup-sh770x.c. It makes sense to share the setup code
between these processors because most hardware blocks are identical
from a software point of view. With this patch the sh770x processors
now have a complete set of vectors that match with the information
provided by the data sheets. This is a big improvement for sh7708.
Vectors for IRQ4 and IRQ5 are enabled by default. Use
plat_irq_setup_pins() if pins IRQ0-3 should be used in IRQ mode.
This patch also unifies the platform device setup code which means
that the rtc driver now has platform data for all sh770x processors.
