[PATCH v5 03/10] ARM: dts: Clean up exynos5250-snow

["Andreas Färber" <afaerber@suse.de>]

Use the new style of referencing inherited nodes and use symbolic names.
Reorder one pinctrl node in GPIO order.

Goal is the alignment of all exynos5250 based device trees for comparison.

Suggested-by: Doug Anderson <dianders@chromium.org>
Signed-off-by: Andreas Färber <afaerber@suse.de>
---
 v4 -> v5:
 * Introduced labels to consistently use new referencing style (Tomasz)
 * Use IRQ_TYPE_* constants
 * Use some more GPIO_ACTIVE_*

 v3 -> v4: Unchanged
 
 v3: New (Doug Anderson)
