regulator: pv88080: Update regulator for PV88080 BB silicon support 



Three files are modified, the driver, header file and the binding document.

Updates for the regulator source file include and .of_match_table entry
and node match checking in the probe() function for a compatible pv88080
silicon type. A new "HVBUCK" is added in source file and added
regsiter definition in header file for pv88080 bb silicion.
The binding documentation changes have been made to reflect these updates.

* Powerventure Semiconductor PV88080 Voltage Regulator



Required properties:

- compatible: "pvs,pv88080".

- reg: I2C slave address, usually 0x49.

- compatible: Must be one of the following, depending on the

  silicon version:

	- "pvs,pv88080" (DEPRECATED)



	- "pvs,pv88080-aa" for PV88080 AA or AB silicon

	- "pvs,pv88080-ba" for PV88080 BA or BB silicon

  NOTE: The use of the compatibles with no silicon version is deprecated.

- reg: I2C slave address, usually 0x49

- interrupts: the interrupt outputs of the controller

- regulators: A node that houses a sub-node for each regulator within the

  device. Each sub-node is identified using the node's name, with valid

  values listed below. The content of each sub-node is defined by the

  standard binding for regulators; see regulator.txt.

  BUCK1, BUCK2, and BUCK3.

  BUCK1, BUCK2, BUCK3 and HVBUCK.
