Subject: clk: samsung: exynos5250: Add MDMA0 clocks
From: Abhilash Kesavan <a.kesavan@xxxxxxxxxxx>
commit 8fb9aeb7a71ef4f3e0613d459a2e1366a7a90469 upstream.
Adds gate clock for MDMA0 on Exynos5250 SoC. This is needed to ensure
that the clock is enabled when MDMA0 is used on systems on which
firmware gates the clockby default.
