Subject: clk: exynos5250: fix sysmmu_mfc{l,r} gate clocks
From: Andrew Bresticker <abrestic@xxxxxxxxxxxx>
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.
