Shaveta Leekha b8bf0adc12 powerpc/mpc85xx: Add DSP side awareness for Freescale Heterogeneous SoCs
The code provides framework for heterogeneous multicore chips based on StarCore
and Power Architecture which are chasis-2 compliant, like B4860 and B4420

It will make u-boot recognize all non-ppc cores and peripherals like
SC3900/DSP CPUs, MAPLE, CPRI and print their configuration in u-boot logs.
Example boot logs of B4860QDS:

U-Boot 2015.01-00232-geef6e36-dirty (Jan 19 2015 - 11:58:45)

CPU0:  B4860E, Version: 2.2, (0x86880022)
Core:  e6500, Version: 2.0, (0x80400120)
Clock Configuration:
       CPU0:1600 MHz, CPU1:1600 MHz, CPU2:1600 MHz, CPU3:1600 MHz,
       DSP CPU0:1200 MHz, DSP CPU1:1200 MHz, DSP CPU2:1200 MHz, DSP CPU3:1200 MHz,
       DSP CPU4:1200 MHz, DSP CPU5:1200 MHz,
       CCB:666.667 MHz,
       DDR:933.333 MHz (1866.667 MT/s data rate) (Asynchronous), IFC:166.667 MHz
       CPRI:600  MHz
       MAPLE:600  MHz, MAPLE-ULB:800  MHz, MAPLE-eTVPE:1000 MHz
       FMAN1: 666.667 MHz
       QMAN:  333.333 MHz

Top level changes include:
(1) Top level CONFIG to identify HETEROGENUOUS clusters
(2) CONFIGS for SC3900/DSP components
(3) Global structures like "cpu_type" and "MPC85xx_SYS_INFO"
    updated for dsp cores and other components
(3) APIs to get DSP num cores and their Mask like:
        cpu_dsp_mask, cpu_num_dspcores etc same as that of PowerPC
(5) Code to fetch and print SC cores and other heterogenous
    device's frequencies
(6) README added for the same
