next PM branch preview

[Kevin Hilman <khilman@deeprootsystems.com>]

Hello,

I've rebased the PM branch on to current linux-omap HEAD (currently
2.6.30-rc4) and it is available from my tree[1] as the branch named
'pm-next'

There's still a couple issues for me to work, out but since people
have been asking, I've made it publicly available.

So far, I have only tested full-chip retention in suspend and PM idle
(not CPUidle) using minimal kernels on the following platforms:

- 3430SDP: initramfs
- RX51: OneNAND rootfs
- OMAP3EVM: initramfs
- Beagle: initramfs

Not tested:
- CPUidle
- DVFS (CPUfreq)

Known issues:
- 3430SDP: CORE pwrdm does not hit retention
- hangs on return from OFF
- OMAP3EVM: debounce used on TS GPIO (in GPIO6) and result in
  "Clock gpio6_dbck didn't enable in 100000 tries"

Also note that I only build minimal kernels using very few drivers.
So I've also added the defconfigs I used for the boards so it's clear
what I'm using to test.  They are named *_pm_defconfig.
