MLK-13793-4 ARM: dts: imx6qdl-sabresd: Add supplies for the SoC internal regulators

The following errors are shown at boot:
  vddarm: bypassed regulator has no supply!
  vddarm: failed to get the current voltage(-517)
  anatop_regulator 20c8000.anatop:regulator-vddcore: failed to register vddarm
  vddsoc: bypassed regulator has no supply!
  vddsoc: failed to get the current voltage(-517)
  anatop_regulator 20c8000.anatop:regulator-vddsoc: failed to register vddsoc
  vddpu: bypassed regulator has no supply!

The SoC internal regulators come from the Freescale PFUZE100 PMIC:
  - SW1AB is connected through VDDARM_IN to LDO_ARM (vddarm)
  - SW1C is connected through VDDSOC_IN to LDO_PU (vddpu) and LDO_SOC (vddsoc)

Add this relationship to the device tree so these regulators have a supply
specified and can be registered properly.
