mpc83xx: Add support for the MPC8349E-mITX

PREREQUISITE PATCHES:

* This patch can only be applied after the following patches have been applied:

  1) DNX#2006090742000024 "Add support for multiple I2C buses"
  2) DNX#2006090742000033 "Multi-bus I2C implementation of MPC834x"
  3) DNX#2006091242000041 "Additional MPC8349 support for multibus i2c"
  4) DNX#2006091242000078 "Add support for variable flash memory sizes on 83xx systems"
  5) DNX#2006091242000069 "Add support for Errata DDR6 on MPC 834x systems"

CHANGELOG:

* Add support for the Freescale MPC8349E-mITX reference design platform.
  The second TSEC (Vitesse 7385 switch) is not supported at this time.
