Subject: [ 09/95] ARM: LPC32xx: Fix interrupt controller init

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

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

From: Roland Stigge <stigge@...com.de>

commit 35dd0a75d4a382e7f769dd0277732e7aa5235718 upstream.

This patch fixes the initialization of the interrupt controller of the LPC32xx
by correctly setting up SIC1 and SIC2 instead of (wrongly) using the same value
as for the Main Interrupt Controller (MIC).
