[PATCH] Add interrupts property to L2x0 OF binding

[Mark Rutland <mark.rutland@arm.com>]

Following the discussion here:
http://lists.ozlabs.org/pipermail/devicetree-discuss/2011-August/007301.html

The L2x0 L2 Cache Controllers support a combined interrupt line
which can be used for several events (e.g. read/write/parity errors on
tag/data RAM, event counter increment/overflow). Unfortunately the
OF binding does not represent the interrupt.

This patch adds an "interrupts" property to the L2x0 OF binding,
representing the combined interrupt line.
