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

DSP side awareness for Freescale heterogeneous multicore chips based on
StarCore and Power Architecture
===============================================================
powerpc/mpc85xx code ve APIs and function to get the number,
configuration and frequencies of all PowerPC cores and devices
connected to them, but it didnt have the similar code ofr HEterogeneous
SC3900/DSP cores and such devices like CPRI, MAPLE, MAPLE-ULB etc.
Code for DSP side awareness provides such functionality for Freescale
Heterogeneous SoCs which are chasis-2 compliant like B4860 and B4420
As part of this feature, following changes have been made:
==========================================================
1. Changed files:
=================
- arch/powerpc/cpu/mpc85xx/cpu.c
Code added in this file to print the DSP cores and other device's(CPRI,
MAPLE etc) frequencies
- arch/powerpc/cpu/mpc85xx/speed.c
Added Defines and code to extract the frequncy information for all
required cores and devices from RCW and System frequency
- arch/powerpc/cpu/mpc8xxx/cpu.c
Added API to get the number of SC cores in running system and Their BIT
MASK, similar to the code written for PowerPC
- arch/powerpc/include/asm/config_mpc85xx.h
Added top level CONFIG to identify presence of HETEROGENUOUS clusters
in the system and CONFIGS for SC3900/DSP components
- arch/powerpc/include/asm/processor.h
- include/common.h
Added newly added Functions Declaration
- include/e500.h
Global structure updated for dsp cores and other components
2. CONFIGs ADDED
================
CONFIG_HETROGENOUS_CLUSTERS - Define for checking the presence of
DSP/SC3900 core clusters
CONFIG_SYS_FSL_NUM_CC_PLLS - Define for number of PLLs
Though there are only 4 PLLs in B4, but in sequence of PLLs from PLL1 -
PLL5, PLL3 is Reserved(as mentioned in RM), so this define contains the
value as 5 not 4, to iterate over all PLLs while coding
CONFIG_SYS_MAPLE - Define for MAPLE Baseband Accelerator
CONFIG_SYS_CPRI - Define for CPRI Interface
CONFIG_PPC_CLUSTER_START - Start index of ppc clusters
CONFIG_DSP_CLUSTER_START - Start index of dsp clusters
Following are the defines for PLL's index that provide the Clocking to
CPRI, ULB and ETVE components
CONFIG_SYS_CPRI_CLK - Define PLL index for CPRI clock
CONFIG_SYS_ULB_CLK - Define PLL index for ULB clock
CONFIG_SYS_ETVPE_CLK - Define PLL index for ETVPE clock
3. Changes in MPC85xx_SYS_INFO Global structure
===============================================
DSP cores and other device's components have been added in this structure.
freq_processor_dsp[CONFIG_MAX_DSP_CPUS] - Array to contain the DSP core's frequencies
freq_cpri - To store CPRI frequency
freq_maple - To store MAPLE frequency
freq_maple_ulb - To store MAPLE-ULB frequency
freq_maple_etvpe - To store MAPLE-eTVPE frequency
