Adding a debugfs entry for detecting the valid HDCP sinks to perform kms_content_protection. In case of dummy HDMI/DP sinks(EDID whisperers without any parsers) IGT will skip the HDCP test on that connector instead of failing it. Hence false alarm are avoided. For serving above purpose this series has pulled out few changes from "Implement HDCP2.2" series under review at https://patchwork.freedesktop.org/series/38254/ "drm/i915: hdcp_check_link only on CP_IRQ" is just a improvement patch for HDCP1.4. Already received the reviewed-by from Sean Paul. v5: DDC/AUX failures are presented as debug logs instead of errors.
