Changes since previous update:
  - ACK IRQ status bits before doing anything else
  - Added multi-master device tree property
  - Do not send STOP commands after interrupt errors
  - Fix SMBUS_QUICK emulation handling
  - Removed highspeed clock code (I will do it in a later patch set)
  - Use the platform_device name for the adapter name
  - Reset for all failed recoveries
  - Removed the "__" prefix from all of the non-thread safe functions

As before, tested on Aspeed 2500 evaluation board and a real platform with an
Aspeed 2520.
