u-boot/drivers/power/Kconfig
Simon Glass 14c251ffe1 power: Add a POWER config 
At present we have SPL_POWER but not piain POWER. This works because
there is a special build rule in Makefile that always includes the
drivers/power directory.

It is better to have all driver directories included by drivers/Makefile
and there is already a rule in there for this purpose. It just needs a
Kconfig for U-Boot proper, so add one.

Update the pmic.h header file so that it defines the old pmic struct
always, when driver model is not in use. That will avoid build errors
for boards which enable POWER but not DM_PMIC.

Enable this option always. That seems strange at first sight, but it
actually but mimics the current Makefile behaviour. Once we can drop the
old PMICs it should be easy enough to rename DM_PMIC to POWWER, or
something similar.

Enable support for power control in U-Boot. This includes support
for PMICs (Power-management Integrated Circuits) and some of the
features provided by PMICs. In particular, voltage regulators can
be used to enable/disable power and vary its voltage. That can be
useful in U-Boot to turn on boot peripherals and adjust CPU voltage
so that the clock speed can be increased. This enables the drivers
in drivers/power, drivers/power/pmic and drivers/power/regulator
as part of a build.
