regulator: dt-bindings: Clean-up active-semi,act8945a duplication

The active-semi,act8945a binding is documented in multiple places. The
charger child node is documented in regulator/active-semi,act8945a.yaml
and power/supply/active-semi,act8945a-charger.yaml. An old text binding
is in mfd/act8945a.txt.

Update the regulator/active-semi,act8945a.yaml with the additional
descriptions and constraints from
power/supply/active-semi,act8945a-charger.yaml, and then remove it and
mfd/act8945a.txt.

-Device-Tree bindings for Active-semi ACT8945A MFD driver
-
-Required properties:
- - compatible: "active-semi,act8945a".
- - reg: the I2C slave address for the ACT8945A chip
-
-The chip exposes two subdevices:
- - a regulators: see ../regulator/act8945a-regulator.txt
- - a charger: see ../power/act8945a-charger.txt
