regulator: pfuze100: add optional disable switch-regulators binding 

This binding is used to keep the backward compatibility with the current
dtb's [1]. The binding informs the driver that the unused switch regulators
can be disabled.
If it is not specified, the driver doesn't disable the switch regulators.

Optional properties:

- fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch

  regulators to save power consumption. Attention, ensure that all important

  regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"

  property. If not present, the switched regualtors are always on and can't be

  disabled. This binding is a workaround to keep backward compatibility with

  old dtb's which rely on the fact that the switched regulators are always on

  and don't mark them explicit as "regulator-always-on".
