From: Andrzej Pietrasiewicz <andrzej.p at samsung.com>
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 scaler to
work properly after domain power on/off sequence.
