[PATCH resend] component: demote bind messages to debug level

[Lucas Stach]

The component bind messages are mostly redundant as most drivers print
a more specific message themselves when binding has succeeded. As they
don't add much value, but can get noisy with a lot of components in the
system demote them to debug level.

These provide useful information when things don't work out right.  For
example, imx-drm's crtc components are completely silent, like Dove's
armada-drm components as well.  etnaviv is actually silent from the
component bind functions: it's only afterwards when we initialise the
GPUs that were found that we print anything there.

So, I don't deem them to be redundant.
