Ventana uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.
The data was chosen to match the PMIC HW defaults, with the following
exception:
ldo6: The HW default is 2.85v. The schematics are unlabelled. Internal
research indicates that 1.8v is correct. Our downstream kernel also uses
1.8v.

v3:
* Switch back to simple-bus compatible value for the /regulators node.
* Added supply properties for all TPS6586x regulators.
* Made SM* children of the new SYS regulator.
* Removed ldo0 configuration, since it isn't used.
v2:
* Made all constraints match the HW defaults to avoid behavior changes,
with exceptions noted above.
* Removed vin-supply properties from LDO nodes; the driver and binding
need to be updated to support specifying the parent regulators before
we can put these into DT.
* Rename vdd_pnl regulator-name to match schematic.
* Added vdd_bl regulator.
* Fix typo in regulator@3 reg property.
* Use the enumerated-bus compatible value for the /regulators node.
* Enhanced all regulator-name properties to list all signal names directly
derived from the regulator pins.
* Added ldo_rtc regulator.

You can addd my ACK for harmony dts file.

Should we say interrupt-controller also here?

This depends on two changes on tps6586x regulator which are not merged yet.
