There was confusion between the array size and the highest ISEL
value possible.

The WM831x series of devices provide three types of LDO:
- General purpose LDOs supporting voltages from 0.9-3.3V
- High performance analogue LDOs supporting voltages from 1-3.5V
- Very low power consumption LDOs intended to support always on
functionality.
This patch adds support for all three kinds of LDO. Each regulator
is probed as an individual platform device with resources used to
provide the register map location of the regulator. Mixed hardware
and software control of regulators is not current supported.

The WM831x series of devices all have 3 DC-DC buck convertors. This
driver implements software control for these regulators via the
regulator API. Use with split hardware/software control of individual
regulators is not supported, though regulators not controlled by
software may be controlled via the hardware control interfaces.

The current settings which can be used with the WM831x current sinks
can't easily be mapped between register values and currents at run
time without a lookup table since the values scale logarithmically
to match the way the human eye interprets brightness. This lookup
table is inclided in the core since several drivers need to use it.
