Change check of DDC status. Instead of silently not reading EDID when in
"IDLE" state [1]. Always read EDID but add a debug log when DDC
controller is in reset.

Change check of DDC status. Instead of silently not reading EDID when in
"IDLE" state [1]. Wait for HDCP being initialized because the EDID and
HDCP block shares memory [2].
