Initial support for Freescale PowerQUICC III MPC85xx system-on-chip family.

The PQ3 is a high performance integrated communications processing system
based on the e500 core, which is an embedded RISC processor that implements
the 32-bit Book E definition of the PowerPC architecture. For details refer
to: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8555E

This port was tested and successfully run on the following members of the PQ3
family: MPC8533, MPC8541, MPC8548, MPC8555.

The following major integrated peripherals are supported:

  * On-chip peripherals bus
  * OpenPIC interrupt controller
  * UART
  * Ethernet (TSEC)
  * Host/PCI bridge
  * QUICC engine (SCC functionality)

This commit brings the main functionality and will be followed by individual
drivers that are logically separate from this base.
