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.
