This is an updated version of "[PATCH v3 13/13] ARM: dts: exynos: Add Samsung Galaxy Tab 3 8.0 boards"[1].

Changed in v5:
- Re-added disabled RTC node instead of deleting it with delete-node

Changed in v4:
- Added touchkey keycodes
- Added audio nodes
- Added MMC aliases
- Fixed dtbs_check warnings
- Fixed indentation in pinctrl sleep state overrides

Changed in v3:
- Addressed review comments
- Removed rtc node (RTC is provided by PMIC)
- Added CPU thermal node
- Fixed dtbs_check warnings
- Added common changes from next/dt

Should pass dtbs_check with no errors, provided that the following patches are present:

Backlight node is adapted to changes from "[PATCH v2 1/4] dt-bindings:
backlight: lp855x: convert to YAML and modernize"[2]. The whole patchset has been merged into the backlight tree.

Touchkey keycode property is added by "[PATCH 1/2] dt-bindings: mms114: Add linux,keycodes property for touch keys"[3]. So far only the bindings part of the patch has been acked, otherwise everything is awaiting review.

Display bindings have been added by "[PATCH v5 1/3] dt-bindings: display:
panel: Add Samsung S6D7AA0 LCD panel controller"[4]. These are already reviewed and merged into the DRM tree.
