Blackfin arch: Fix Bug - System with EMAC driver enabled - Core not idling
- Disable all bits in SIC_IWR unless we are going into a real (DPMC)
power saving mode. Any Interrupt can wake the core form it's idle state.
- Remove deep sleep mode as it is not going to be used anywhere:
We support sleep, sleep deeper and hibernate.
