ARM: OMAP: SmartReflex: Move smartreflex driver to drivers/

Browse source 
After a clean-up of the interfaces the OMAP Smartreflex IP driver is now a
generic driver. Move it to drivers/power/avs/.

The build is controlled by the following Kconfig options:
 . CONFIG_POWER_AVS: general knob for Adaptive Voltage Scaling support,
 . CONFIG_POWER_AVS_OMAP: AVS(Adaptive Voltage Scaling)
   support on OMAP containing the version 1 or version 2 of the SmartReflex IP,
 . CONFIG_POWER_AVS_OMAP_CLASS3: Class 3 implementation of Smartreflex.

menuconfig POWER_AVS
tristate "Adaptive Voltage Scaling class support"
help
AVS is a power management technique which finely controls the
operating voltage of a device in order to optimize (i.e. reduce)
its power consumption.
At a given operating point the voltage is adapted depending on
static factors (chip manufacturing process) and dynamic factors
(temperature depending performance).
AVS is also called SmartReflex on OMAP devices.
Say Y here to enable Adaptive Voltage Scaling class support.
