Commit 94aed538e032 ("ARM: dts: exynos: Add async-bridge clock to MFC
power domain for Exynos5420") fixed an imprecise external abort error
when the MFC registers were tried to be accessed and the needed clock
for the asynchronous bridges were gated.
But according to the Exynos5420 manual the "Gating AXI clock for MFC"
is not CLK_ACLK333 but CLK_MFC.
The end effect is the same because CLK_ACLK333 is a parent of CLK_MFC
but the correct clock should be used instead.
