Subject: [PATCH 3.13 34/40] pinctrl: imx27: fix wrong offset to ICONFB

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

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

From: Chris Ruehl <chris.ruehl@...ys.com.hk>

commit 795779df22afc8bdee4e9fbe5c18c47e44974d75 upstream.

The offset to ICONFB was incorrect, this patch set the correct value 0x14.
dev_dbg in function imx1_write_2bit print the wrong address and had been
moved after address calculation.
