The DESHDCP clock is required only by the DES-HDCP block within HDMI in DSS. However, if the clock isn't set before DSS clock domian is enabled, the clock domain never comes out of idle state. The DESHDCP clock is enabled/disabled at the DSS boundary by the bit DSS_DESHDCP_CLKEN in CTRL_CORE_CONTROL_IO_2. Add dss_deshdcp gate-clock node under dra7-ctrl-core. There are separate bit fields for enabling and disabling the clock. We just map the enable bit since this clock doesn't cause any impact if left enabled.
