msm: mdss: hdcp_1x: enable HDP irq only for DP client 



 HDCP driver provides a common interface for both Display port
 and HDMI clients. As HPD IRQ enable  API is valid only display
 Port, make sure it is handled gracefully when called
 from HDMI client so that invalid resource access can be avoided.
