hdmitx: force to update glitch time after hdcp22 unmux [1/1]

PD#SWPL-11894

Problem:
glitch time in bl31 may not be updated after hdcp22 unmux,
because get hdcp auth result function in bl31 will not be
called after hdcp mode set to 0. In a result, the glitch
hdcp22 result may take place of the actual hdcp22 auth
status after mode change, and feedback to systemcontrol
to clear/set video mute by wrong

Solution:
force to update glitch time after hdcp22 unmux
