Convert the bindings of Qualcomm SPMI regulators to DT schema.

Signed-off-by: Robert Marko <robimarko@gmail.com>
---
I am aware that syscon alone is not really acceptable, its converted
directly from the old text bindings.

There is also the issue of some MSM8994, MSM8996 and APQ8096 devices using
'#address-cells', '#size-cells', some even defining reg property for
regulators.

Any advice on how to solve these issues is appreciated.

Changes in v2:
* Remove the forgotten text bindings
* Move allOf after patternProperties
* Use my private email as the maintainer email

You miss here interrupts+names.

No quotes around this.

We should not allow any supply, but rather a strictly defined pattern.

What I actually prefer is to see something like this:
https://lore.kernel.org/all/20220426105501.73200-3-krzysztof.kozlowski@linaro.org/
but that's not a requirement. Some specific pattern is enough.

s1111 should not be a valid regulator. :)
Neither s000000.

Ok, will fix up in v3.

While we are here,
any ideas about the DTS-s that use reg and #address/size-cells for
regulator subnodes and syscon?

Ok, I will remove them, it's a bit confusing as most bindings use
quotes around refs.

I have implemented this style of supply matching per compatible in v3 as
trying to regex does not seem to cover matching them properly.

Got it, have implemented a much stricter regex in v3.

Ideas for what exactly? It looks like a more of a subsystem convention,
whether to use unit addresses for children which are not real devices
(LEDs use unit addresses, regulators do not).

-The content of each sub-node is defined by the standard binding for regulators -
-see regulator.txt - with additional custom properties described below:
-
-- regulator-initial-mode:
-	Usage: optional
-	Value type: <u32>
-	Description: 2 = Set initial mode to auto mode (automatically select
-		    between HPM and LPM); not available on boost type
-		    regulators.
-
-		    1 = Set initial mode to high power mode (HPM), also referred
-		    to as NPM. HPM consumes more ground current than LPM, but
-		    it can source significantly higher load current. HPM is not
-		    available on boost type regulators. For voltage switch type
-		    regulators, HPM implies that over current protection and
-		    soft start are active all the time.
-
-		    0 = Set initial mode to low power mode (LPM).
-
-- qcom,ocp-max-retries:
-	Usage: optional
-	Value type: <u32>
-	Description: Maximum number of times to try toggling a voltage switch
-		     off and back on as a result of consecutive over current
-		     events.
-
-- qcom,ocp-retry-delay:
-	Usage: optional
-	Value type: <u32>
-	Description: Time to delay in milliseconds between each voltage switch
-		     toggle after an over current event takes place.
-
-- qcom,pin-ctrl-enable:
-	Usage: optional
-	Value type: <u32>
-	Description: Bit mask specifying which hardware pins should be used to
-		     enable the regulator, if any; supported bits are:
-			0 = ignore all hardware enable signals
-			BIT(0) = follow HW0_EN signal
-			BIT(1) = follow HW1_EN signal
-			BIT(2) = follow HW2_EN signal
-			BIT(3) = follow HW3_EN signal
-
-- qcom,pin-ctrl-hpm:
-	Usage: optional
-	Value type: <u32>
-	Description: Bit mask specifying which hardware pins should be used to
-		     force the regulator into high power mode, if any;
-		     supported bits are:
-			0 = ignore all hardware enable signals
-			BIT(0) = follow HW0_EN signal
-			BIT(1) = follow HW1_EN signal
-			BIT(2) = follow HW2_EN signal
-			BIT(3) = follow HW3_EN signal
-			BIT(4) = follow PMIC awake state
-
-- qcom,vs-soft-start-strength:
-	Usage: optional
-	Value type: <u32>
-	Description: This property sets the soft start strength for voltage
-		     switch type regulators; supported values are:
-			0 = 0.05 uA
-			1 = 0.25 uA
-			2 = 0.55 uA
-			3 = 0.75 uA
-
-- qcom,saw-slave:
-	Usage: optional
-	Value type: <boo>
-	Description: SAW controlled gang slave. Will not be configured.
-
-- qcom,saw-leader:
-	Usage: optional
-	Value type: <boo>
-	Description: SAW controlled gang leader. Will be configured as
-		     SAW regulator.

-Example:
-
-	regulators {
-		compatible = "qcom,pm8941-regulators";
