msm_fb: HDMI: Do not add HDCP reauth timer during probe

Currently all HDMI/HDCP timers are initialized in the driver's
probe function with a maximum possible expiration value. However,
the 32-bit jiffies value is initialized in the kernel so as to
wrap 5 minutes after boot. This results in the HDCP timer being
fired 5 minutes after boot even though reauthentication is not
necessary. This change fixes this issue by not starting the HDCP
reauth timer during probe. The timer is only started when an
authentication failure is detected from an existing valid HDCP
session.
