Add INTCS support for the sh73a0 processor.

The interrupts on the sh73a0 processor are managed
through controllers such as GIC, INTCS and INTCA.

The ARM cores use the GIC as primary interrupt
controller and the INTCS and INTCA are hanging off
the GIC as cascaded interrupt controllers.

Peripherals connected both to the GIC and the INTC
controllers should if possible only use the GIC.

If no GIC connection is available then INTCS and
INTCA may be used instead.

Fix interrupt priority level handling on SH-Mobile ARM.

SH-Mobile ARM platforms using multiple interrupt priority
levels need this patch to fix a potential dead lock that
may occur if multiple interrupts with different levels
are pending simultaneously.

The default INTC configuration is to use the same priority
level for all interrupts, so this issue does not trigger by
default. It is however common for board code to override the
interrupt priority for certain interrupt sources depending
on the application. Without this fix such boards may lock up.

In detail, this patch updates the INTC code in entry-macro.S
to make sure that the INTLVLA register gets set as expected.

To trigger this bug modify the board specific code to adjust
the interrupt priority level for the ethernet chip. After
changing the priority level simply use flood ping to drown
the board with interrupts.

This patch applies to INTCA-based processors such as sh7372,
sh7377 and sh7372. GIC-based processors are not affected.

Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.
