[PATCH 4/5] ARM: dts: imx6ull-tarragon-common: Fix i.MX6ULL DVFS

[Stefan Wahren <wahrenst@gmx.net>]

During mainlining of the Tarragon boards, we missed to wire up reg_arm
and reg_soc from PMIC to the i.MX6ULL, which result in a constant voltage
during DVFS. While fixing this, give the regulator a better node reference.
