Subject: [PATCH 08/94] clk: samsung: exynos4: Remove SRC_MASK_ISP gates

From: Tomasz Figa <t.figa@...sung.com>

ISP special clocks have dedicated gating registers and so MUX SRC_MASK
register should not be used. This patch fixes the problem of
Exynos4x12-based boards freezing on system suspend, because those
mux outputs need not to be masked while suspending.
