powerpc/mpc8308rdb: support for MPC8308RDB board from Freescale

This patch adds support for MPC8308RDB development board from
Freescale.
Supported devices:
 DUART
 Dual Ethernet
 NOR and NAND flashes
 I2C
 USB in peripheral mode

PCIE support is broken by the commit 3da34aa ("powerpc/fsl: Support
unique MSI addresses per PCIe Root Complex"). Works after revert.
