[PATCH]PM QOS refresh against next-20100430

[mark gross]

The following is a refresh of the PM_QOS implementation, this patch
updates some documentation input I got from Randy.

This patch changes the string based list management to a handle base
implementation to help with the hot path use of pm-qos, it also renames
much of the API to use "request" as opposed to "requirement" that was
used in the initial implementation.  I did this because request more
accurately represents what it actually does.

Also, I added a string based ABI for users wanting to use a string
interface.  So if the user writes 0xDDDDDDDD formatted hex it will be
accepted by the interface.  (someone asked me for it and I don't think
it hurts anything.)

I really would like to get this refresh taken care of.  Its been taking
me too long to close this.  please review or include it in next.

Thanks!
