video: tegra: dc: disable disp.emc clock when 0 new rate is requested
Not disabling emc clock when it's being set to zero results in incorrect
reference count when a call is made to clear bandwidth. This happens when
two worker threads try to handle dc emc rate. A deep-sleep/wake-up cycle
easily shows this scenario.
With this fix, disp.emc's ref count is properly managed even after multiple
deep-sleep/wake-up cycles.
