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.

This patch unifies the cpu specific interrupt setup functions for
interrupt controller blocks such as ipr, intc2 and intc. There is no
point in having separate functions for each interrupt controller, so
let's clean this up.

This patch reworks the ipr code by grouping the offset array together
with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct
irq_chip. The idea behind putting struct irq_chip in there is that we
can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged
intc2 code.
One logic change has been made - the original ipr code enabled the
interrupts by default but with this patch they are all disabled by
default.

hp6xx requires some additional IRQs that aren't currently enabled in
the SH7709 setup code. Wire them up.

This fixes up shmin (and SH7706/SH7708) IPR support for some of the
recent API changes.

This adds some simple setup code for most of the CPU subtypes,
primarily simple platform device registration.
