[PATCH 06/14] ARM: dts: imx6ul-var-som: Factor out common parts for all CPU variants

[Hugo Villeneuve <hugo@hugovil.com>]

From: Hugo Villeneuve <hvilleneuve@dimonoff.com>

Factor out the parts on the Variscite VAR-SOM-6UL [1] that are common to
all CPU variants (6UL, 6ULL, etc).

This will simplify adding future dedicated device tree files for each CPU
variant.
