mali-dp interface cleanups.

* 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld:
  drm: mali-dp: Disable planes when their CRTC gets disabled.
  drm: mali-dp: Separate static internal data into a read-only structure.
  drm/arm: Replace instances of drm_dev_unref with drm_dev_put.
  drm: mali-dp: switch to drm_*_get(), drm_*_put() helpers

3 hdlcd fixes/cleanups

* 'for-upstream/hdlcd' of git://linux-arm.org/linux-ld:
  drm/arm: Replace instances of drm_dev_unref with drm_dev_put.
  drm: Fix checkpatch issue: "WARNING: braces {} are not necessary for single statement blocks."
  drm: hdlcd: Update PM code to save/restore console.

Replace drm_dev_unref with drm_dev_put as it is more consistent
with kernel coding style. Done using the following semantic
patch by coccinelle.

Make sure only the planes on the active CRTCs get committed and
that all planes on the disabled CRTCs get turned off.

The malidp_hw_device structure that the driver uses to handle the
differences between versions of the IP contains both non-changeable
data and fields that get updated at probe time. Previously we were
copying the read-only part into allocated memory, but that can be
completely avoided by splitting the structure into a read-only part
and keeping the runtime modifiable fields into the old structure.

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.
