cw1200: Wakeup on wireless (WoW) is implemented.
+ Core and SDIO power management is implemented as defined in
wireless-next v3.0-rc4.
+ SDD is cached to avoid disk access at suspend/resume time.
TODO:
- WoW conditions and filtering are not yet implemented.
- BUG: Late interrupts (coming after suspend() callback but
before the actual suspend) are not detected as wakeup sources.
Universal (Android/GLK) way of waking up halfly-suspended system
to be found.
