powerpc/85xx: Add BSC9132QDS support

BSC9132QDS is a Freescale reference design board for BSC9132 SoC.
BSC9132 SOC is an integrated device that targets the evolving Microcell,
Picocell, and Enterprise-Femto base station market subsegments.
It combines Power Architecture e500v2 and DSP StarCore SC3850 core
technologies with MAPLE-B2F baseband acceleration processing elements.

BSC9132QDS Overview
 --------------------
  2Gbyte DDR3 (on board DDR), Dual Ranki
  32Mbyte 16bit NOR flash
  128Mbyte 2K page size NAND Flash
  256 Kbit M24256 I2C EEPROM
  128 Mbit SPI Flash memory
  SD slot
  USB-ULPI
  eTSEC1: Connected to SGMII PHY
  eTSEC2: Connected to SGMII PHY
  PCIe
  CPRI
  SerDes
  I2C RTC
  DUART interface: supports one UARTs up to 115200 bps for console display

Apart from the above it also consists various peripherals to support DSP
functionalities.

This patch adds support for mainly Power side functionalities and peripherals
