All regulators have ascendant voltage list in this driver.
Thus use regulator_map_voltage_ascend is more efficient than the default
regulator_map_voltage_iterate.

Moving regulator node parsing to regulator driver in place
of parsing it on mfd driver.
The motivation for this change are:
- MFD core driver should not depends on regulator and able
to instantiate device without regulator.
- The API for matching regulators are in regulator core and
it is good that regulator driver only calls this API.
- Regulator specific support should be in regulator driver only
to ease any enhancement/modification for regulators.
- The regulator driver is now registered as mfd sub device and
all regulator registration is done from single probe call.

Device have SYS rail which is always ON. It is system power bus. LDO5
and LDO_RTC get powered through this rail internally. Add support for
this rail and make the LDO5/LDO_RTC supply by it. Update document
accordingly.

Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.
The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.

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.
