hdmitx: don't ignore hotplug out event [1/1]

Browse Source 
PD#SWPL-21288

Problem:
if there's a short hpd low pulse(eg 10ms, plugout->plugin event),
the plugout event will be ignored in driver, and the subsequent plugin
event can't be handled by systemcontrol because systemcontrol can't
get the later plugin uevent when successive plugin uevent come.
But hdcp is disabled in driver, video will be mute after systemcontrol
detect hdcp auth status fail.

Solution:
don't ignore any hpd low pluse

Verify:
