Change the interface used by set_voltage() to report the selected value
to the regulator core in terms of a selector used by list_voltage().
This allows the regulator core to know the voltage that was chosen
without having to do an explict get_voltage(), which would be much more
expensive as it will generally access hardware.

Currently the pcf50633-regulator driver data is set to the pcf50633 core
structure, but the pcf50633-regulator remove handler assumes that it is set to
the regulator device. This patch fixes the issue by accessing the pcf506533
core structure through its parent device and setting the driver data to the
regulator device.

This patch implements list_voltage for the pcf50644 regulator driver.
As the voltages are linearly scaled the code to convert register values to
voltages can be reused and most of the code can be shared with get_voltage.

Regulators need to be available early in init in order to allow them
to be available for consumers when requested. This is generally done
by registering them at subsys_initcall() time but not all regulator
drivers have done that. Convert these drivers to do so in order to
mimimise future support.

Rather than having the regulator init data read from the platform_data
member of the struct device that is registered for the regulator make
the init data an explict argument passed in when registering. This
allows drivers to use the platform data for their own purposes if they
wish.
