regulator: da9055: Fully convert to GPIO descriptors

The DA9055 regulator was touched before, requireing enable GPIOs
to be passed from pdata.

As we have a device for each regulator, obtain the three gpios
ren ("regulator enable"), rsel ("regulator select") and the
ena ("enable") GPIO associated with the regulator enable
directly from the device and cut down on the amount of
GPIO numbers passed as platform data.

The ren and rsel are just requested as inputs: these are
actually handled by hardware. The ena gpios are driven
actively by the regulator core.

There are no in-tree users, but the regulators are instantiated
from the (undocumed) device tree nodes with "dlg,da9055-regulator"
as compatible, and by simply adding regulator-enable-gpios,
regulator-select-gpios and enable-gpios to this DT node, all
will work as before.

regulator: da9055: Pass descriptor instead of GPIO number

When setting up a fixed regulator on the DA9055, pass a descriptor
instead of a global GPIO number. This facility is not used in the
kernel so we can easily just say that this should be a descriptor
if/when put to use.

regulator: DA9055 regulator driver

This is the Regulator patch for the DA9055 PMIC and has got dependency on
the DA9055 MFD core.

This patch support all of the DA9055 regulators. The output voltages are
fully programmable through I2C interface only. The platform data with regulation
constraints is passed down from the board to the regulator.

This patch is functionaly tested on SMDK6410 board. DA9055 Evaluation board
was connected to the SMDK6410 board.
