PM / AVS: SmartReflex: use omap_sr * for enable/disable interface

SmartReflex driver interface is natively divided to two parts:

- external SmartReflex interface
- interface between SmartReflex driver and SmartReflex Class

Functions which belong to AVS class interface can use
struct omap_sr* instead of struct voltatedomain*, to provide a
direct connection between SR driver and SR class. This allows
us to optimize and not do additional lookups where none is
required.

sr_enable() and sr_disable() are interface functions between
SR driver and SR class. They are typically used by Class driver
to enable/disable SmartReflex hardware module.
Now they take struct omap_sr* as input parameter.

OMAP3: PM: Adding smartreflex class3 driver

Smartreflex Class3 implementation continuously monitors
silicon performance and instructs the Voltage Processors
to increase or decrease the voltage.
This patch adds smartreflex class 3 driver. This driver hooks
up with the generic smartreflex driver smartreflex.c to abstract
out class specific implementations out of the generic driver.

Class3 driver is chosen as the default class driver for smartreflex.
If any other class driver needs to be implemented, the init of that
driver should be called from the board file. That way the new class driver
will over-ride the Class3 driver.
