Subject: clk: samsung: exynos5250: Fix ACP gate register offset
From: Abhilash Kesavan <a.kesavan@xxxxxxxxxxx>
commit 3bf34666a0cce5234ac677ed2fbe5cea82c71329 upstream.
The CLK_GATE_IP_ACP register offset is incorrectly listed making
definition of g2d clock incorrect, which may lead to system failures
when trying to use G2D on systems on which firmware gates this clock
by default. Fix this and the register ordering as well.
