power: regulator: Add a driver for AXP PMIC regulators
This driver handles most voltage regulators found in X-Powers AXP PMICs.
It is based on, and intended to replace, the regulator driver in TF-A.
AXP PMIC regulators can be divided into 6 categories:
- Switches without voltage control => fully supported.
- Single linear range => fully supported.
- Two linear ranges, "step" and "2 * step" => fully supported.
- Two linear ranges, "step" and "5 * step" => only the first range is
supported. No boards are known to use the second range.
- Non-linear voltage values => fully supported.
- LDOs shared with GPIO pins => not supported.
