sun50iw1p1: Rewrite PMIC driver.
The existing API to interact with the PMIC (AXP803) offers
low-level calls to read and write PMIC registers.
This patch adds two high-level APIs:
* regulator-level API
* task-level API
The regulator-level API allows to enable, disable, and set
the voltage level of regulators. The regulators are named by IDs
in the form of AXP803_<regulator> (e.g. AXP803_DCDC2).
The task-level API allows to perform a batch of regulator-level
calls. Using this API allows to keep many invokations of the
regulator-level API compact.
