Subject: [PATCH 3.13.y-ckt 23/95] ARM: S3C64XX: Use fixed IRQ bases to avoid conflicts on Cragganmore

3.13.11-ckt21 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Charles Keepax <ckeepax@...nsource.wolfsonmicro.com>

commit 4e330ae4ab2915444f1e6dca1358a910aa259362 upstream.

There are two PMICs on Cragganmore, currently one dynamically assign
its IRQ base and the other uses a fixed base. It is possible for the
statically assigned PMIC to fail if its IRQ is taken by the dynamically
assigned one. Fix this by statically assigning both the IRQ bases.
