regulator: Fixes for -rc1

Browse Source 
A bunch of smallish fixes that came up during the merge window as
 things got more testing - even more fixes from Axel, a fix for error
 handling in more complex systems using -EPROBE_DEFER and a couple of
 small fixes for the new dummy regulators.

Anatop Voltage regulators
Required properties:
- compatible: Must be "fsl,anatop-regulator"
- anatop-reg-offset: Anatop MFD register offset
- anatop-vol-bit-shift: Bit shift for the register
- anatop-vol-bit-width: Number of bits used in the register
- anatop-min-bit-val: Minimum value of this register
- anatop-min-voltage: Minimum voltage of this regulator
- anatop-max-voltage: Maximum voltage of this regulator
Any property defined as part of the core regulator
binding, defined in regulator.txt, can also be used.
Example:
regulator-vddpu {
compatible = "fsl,anatop-regulator";
regulator-name = "vddpu";
regulator-min-microvolt = <725000>;
regulator-max-microvolt = <1300000>;
regulator-always-on;
anatop-reg-offset = <0x140>;
anatop-vol-bit-shift = <9>;
anatop-vol-bit-width = <5>;
anatop-min-bit-val = <1>;
anatop-min-voltage = <725000>;
anatop-max-voltage = <1300000>;
