Michael Hennerich 56f5f59052 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.

Michael Hennerich 68e2fc78e5 Blackfin arch: Fix bug - Kernel does not boot if re-program clocks 
Don't write conflicting data to EBIU_SDBCTL after the SDRAM is
configured. This can cause data corruption, since we might change SDRAM
row and column addressing modes.

Jean Delvare 3760f73671 i2c: Convert most new-style drivers to use module aliasing 
Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.
