powerpc/mpc85xx: Add BSC9132/BSC9232 processor support

The BSC9132 is a highly integrated device that targets the evolving
 Microcell, Picocell, and Enterprise-Femto base station market subsegments.

 The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850
 core technologies with MAPLE-B2P baseband acceleration processing elements
 to address the need for a high performance, low cost, integrated solution
 that handles all required processing layers without the need for an
 external device except for an RF transceiver or, in a Micro base station
 configuration, a host device that handles the L3/L4 and handover between
 sectors.

 The BSC9132 SoC includes the following function and features:
    - Power Architecture subsystem including two e500 processors with
	512-Kbyte shared L2 cache
    - Two StarCore SC3850 DSP subsystems, each with a 512-Kbyte private L2
	cache
    - 32 Kbyte of shared M3 memory
    - The Multi Accelerator Platform Engine for Pico BaseStation Baseband
      Processing (MAPLE-B2P)
    - Two DDR3/3L memory interfaces with 32-bit data width (40 bits including
      ECC), up to 1333 MHz data rate
    - Dedicated security engine featuring trusted boot
    - Two DMA controllers
         - OCNDMA with four bidirectional channels
         - SysDMA with sixteen bidirectional channels
    - Interfaces
        - Four-lane SerDes PHY
	    - PCI Express controller complies with the PEX Specification-Rev 2.0
        - Two Common Public Radio Interface (CPRI) controller lanes
	    - High-speed USB 2.0 host and device controller with ULPI interface
        - Enhanced secure digital (SD/MMC) host controller (eSDHC)
	    - Antenna interface controller (AIC), supporting four industry
		standard JESD207/four custom ADI RF interfaces
       - ADI lanes support both full duplex FDD support & half duplex TDD
       - Universal Subscriber Identity Module (USIM) interface that
	   facilitates communication to SIM cards or Eurochip pre-paid phone
	   cards
       - Two DUART, two eSPI, and two I2C controllers
       - Integrated Flash memory controller (IFC)
       - GPIO
     - Sixteen 32-bit timers
