[PATCHv4 0/8] ARM: OMAP4: core retention support

[Tero Kristo]

Changes compared to previous version:

- rebased on top of 3.4
- added back TEMP patch for preventing DSP wakeup as Paul's powerdomain
  fixes are not yet in (patch #2)
- added open switch retention support (OSWR), can be enabled by
  echo 1 > /debug/pm_debug/enable_oswr_mode
- fixed support for 4460 (added patch #3)

Applies on top of mainline 3.4 + iochain set. May kind of work without
the iochain set but waking up from retention might be impossible.

Tested both CSWR + OSWR modes on omap4430 EMU blaze + omap4460 GP panda.
