ARM: 7023/1: L2x0: Add interrupts property to OF binding
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 added in c519ecf2 ("ARM: 7009/1: l2x0: Add OF based
initialization") does not represent the interrupt.
This patch adds an "interrupts" property to the L2x0 OF binding,
representing the combined interrupt line.
