Subject: [PATCH 3.12 63/77] clk: exynos5250: fix sysmmu_mfc{l,r} gate clocks

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

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

From: Andrew Bresticker <abrestic@...omium.org>

commit 97c3557c3e0413efb1f021f582d1459760e22727 upstream.

The gate clocks for the MFC sysmmus appear to be flipped, i.e.
GATE_IP_MFC[2] gates sysmmu_mfcl and GATE_IP_MFC[1] gates sysmmu_mfcr.
Fix this so that the MFC will start up.
