[RESEND PULL] drm: atmel-hlcdc: various improvements

[Boris Brezillon]

Hi Dave,

I've reformated the PR to use a branch name instead of a commit hash.
Sorry for the inconvenience, I'll try to be more careful for my future
PRs.

This PR contains several improvement and cleanup patches for the
atmel-hlcdc driver to be applied on drm-next (targeting 4.7).

Best Regards,

Boris
