[PATCH] [RFC] ARM: dts: imx6sx-sdb: Drop OPP hackery

[marex@denx.de (Marek Vasut)]

The imx6sx-sdb has one power supply that drives both VDDARM_IN
and VDDSOC_IN, which is the sw1a regulator on the PFUZE PMIC.
Connect both inputs to the sw1a regulator on the PMIC and drop
the OPP hackery which is no longer needed as the power framework
will take care of the regulator configuration as needed.

Note: Fabio, if you have a chance, please give this a spin and see
      if this works.
