regulator: Updates for v3.13

Browse Source 
Lots of driver updates here plus some nice new core features, the main
 one being the first:
 
  - Enable support for providing a dummy regulator when we know that one
    must exist for the device to be functional.  This makes it much
    easier to add regulator support to drivers since we don't require
    that the machine integration for all systems using the device be
    updated to provide regulators.
  - Substantial reduction in the amount of busy waiting done while
    waiting for enables to complete.
  - Allow MFDs to distribute regulator supplies to child devices so we
    don't have to expose the internal structure of MFDs outside of the
    driver.
  - Managed registeration for regulators.

Regulator of AMS AS3722 PMIC.
Name of the regulator subnode must be "regulators".
Optional properties:
--------------------
The input supply of regulators are the optional properties on the
regulator node. The AS3722 is having 7 DCDC step-down regulators as
sd[0-6], 10 LDOs as ldo[0-7], ldo[9-11]. The input supply of these
regulators are provided through following properties:
vsup-sd2-supply: Input supply for SD2.
vsup-sd3-supply: Input supply for SD3.
vsup-sd4-supply: Input supply for SD4.
vsup-sd5-supply: Input supply for SD5.
vin-ldo0-supply: Input supply for LDO0.
vin-ldo1-6-supply: Input supply for LDO1 and LDO6.
vin-ldo2-5-7-supply: Input supply for LDO2, LDO5 and LDO7.
vin-ldo3-4-supply: Input supply for LDO3 and LDO4.
vin-ldo9-10-supply: Input supply for LDO9 and LDO10.
vin-ldo11-supply: Input supply for LDO11.
Optional nodes:
--------------
- regulators : Must contain a sub-node per regulator from the list below.
Each sub-node should contain the constraints and initialization
information for that regulator. See regulator.txt for a
description of standard properties for these sub-nodes.
Additional custom properties are listed below.
sd[0-6], ldo[0-7], ldo[9-11].
Optional sub-node properties:
----------------------------
ams,ext-control: External control of the rail. The option of
this properties will tell which external input is
controlling this rail. Valid values are 0, 1, 2 ad 3.
0: There is no external control of this rail.
1: Rail is controlled by ENABLE1 input pin.
2: Rail is controlled by ENABLE2 input pin.
3: Rail is controlled by ENABLE3 input pin.
ams,enable-tracking: Enable tracking with SD1, only supported
by LDO3.
