clk: samsung: Fix m2m scaler clock on Exynos542x
[ Upstream commit c07c1a0f68d0f2f7ca9aff924e2772526027b019 ]
The TOP "aclk400_mscl" clock should be kept enabled all the time
to allow proper access to power management control for MSC power
domain and devices that are a part of it. This change is required
for the scaler to work properly after domain power on/off sequence.
