[PATCH 2/2] powerpc/fsl-booke: Add initial T1042RDB_PI board support

[Priyanka Jain]

T1042RDB_PI is Freescale Reference Design Board supporting the T1042
QorIQ Power Architecture™ processor. T1042 is a reduced personality
of T1040 SoC without Integrated 8-port Gigabit. The board is designed
with low power features targeted for Printing Image Market.

T1042RDB_PI is  similar to T1040RDB board with few differences like
it has video interface, supports T1042 personality only

T1042RDB_PI board Overview
-----------------------
- SERDES Connections, 8 lanes supporting:
    	- PCI
    	- SATA 2.0
- DDR Controller
    	- Supports rates of up to 1600 MHz data-rate
    	- Supports one DDR3LP UDIMM
-IFC/Local Bus
    	- NAND flash: 1GB 8-bit NAND flash
    	- NOR: 128MB 16-bit NOR Flash
- Ethernet
    	- Two on-board RGMII 10/100/1G ethernet ports.
    	- PHY #0 remains powered up during deep-sleep
- CPLD
- Clocks
    	- System and DDR clock (SYSCLK, “DDRCLK”)
    	- SERDES clocks
- Power Supplies
- USB
    	- Supports two USB 2.0 ports with integrated PHYs
    	- Two type A ports with 5V at 1.5A per port.
- SDHC
    	- SDHC/SDXC connector
- SPI
    	- On-board 64MB SPI flash
- I2C
    	- Device connected: EEPROM, thermal monitor, VID controller, RTC
- Other IO
    	- Two Serial ports
    	- ProfiBus port

Add support for T1042RDB_PI board:
    -add device tree
    -Add entry in corenet_generic.c, as it is similar to other corenet platforms
