explicit selection of write-back/write-through/off configurations.
All of the cache flushing routines are optimized away for the off

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.

In the SH-3/4 TLB access violation path we were enabling IRQs before
the call in to trace_hardirqs_on(), which ended up triggering:

        if (DEBUG_LOCKS_WARN_ON(!irqs_disabled()))
                return;

in kernel/lockdep.c:2031. Fix this up by removing the early re-enable,
we were already re-enabling IRQs post-trace_hardirqs_on() already, so
the semantics are now as was initially intended.

This is the second version of the shared interrupt controller patch
for the sh architecture, fixing up handling of intc_reg_fns[].

The three main advantages with this controller over the existing
ones are:

	- Both priority (ipr) and bitmap (intc2) registers are
	  supported
	- External pin sense configuration is supported, ie edge
	  vs level triggered
	- CPU/Board specific code maps 1:1 with datasheet for
	  easy verification

This controller can easily coexist with the current IPR and INTC2
controllers, but the idea is that CPUs/Boards should be moved over
to this controller over time so we have a single code base to
maintain.

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.
