Subject: [PATCH v3 04/15] drm/connector: hdmi: Add missing bpc debug info
 to hdmi_try_format_bpc()

The very first debug message in hdmi_try_format_bpc() is incomplete, as
it doesn't provide the given bpc in addition to the tried format.

Add the missing debug information and drop the now redundant message
from hdmi_compute_config().
