drm/i915: hdcp1.4 CP_IRQ handling and SW encryption tracking
"hdcp_encrypted" flag is defined to denote the HDCP1.4 encryption status.
This SW tracking is used to determine the need for real hdcp1.4 disable
and hdcp_check_link upon CP_IRQ.
On CP_IRQ we filter the CP_IRQ related to the states like Link failure
and reauthentication req etc and handle them in hdcp_check_link.
CP_IRQ corresponding to the authentication msg availability are ignored.
WARN_ON is added for the abrupt stop of HDCP encryption of a port.
v2:
bool is used in struct for the cleaner coding. [Daniel]
check_link work_fn is scheduled for cp_irq handling [Daniel]
v3:
rebased.
