Powerdomains: add OMAP2/3 powerdomain code, and common OMAP type bitfield

Hello,

this patch series adds a hardware control and monitoring interface for OMAP2/3 powerdomains. The interface is fully documented in the code.

The series also adds a common OMAP chip type detection bitfield for use with powerdomain and clockdomain structures; it is planned to expand its use to the clock framework in the future.

Powerdomain code tested on 3430SDP ES2.1; also boot-tested on N800.

Many people at Nokia and TI provided commentary and review during the development of the powerdomain patches. Particular help came from (in alphabetical order): Jouni Högander, Tony Lindgren, Sakari Poussa, Igor Stoppa, and Richard Woodruff.

Comments welcome,

- Paul
