powerpc/p3060qds: Add board related support for P3060QDS platform

The P3060QDS is a Freescale reference board for the six-core P3060 SOC.

P3060QDS Board Overview:
 Memory subsystem:
  - 2G Bytes unbuffered DDR3 SDRAM SO-DIMM(64bit bus)
  - 128M Bytes NOR flash single-chip memory
  - 16M Bytes SPI flash
  - 8K Bytes AT24C64 I2C EEPROM for RCW
 Ethernet:
  - Eight Ethernet controllers (4x1G + 4x1G/2.5G)
  - Three VSC8641 PHYs on board (2xRGMII + 1xMII)
  - Suport multiple Vitesse VSC8234 SGMII Cards in Slot1/2/3
 PCIe: Two PCI Express 2.0 controllers/ports
 USB:  Two USB2.0, USB1(TYPE-A) and USB2(TYPE-AB) on board
 I2C:  Four I2C controllers
 UART: Supports two dUARTs up to 115200 bps for console
 RapidIO:  Two RapidIO, sRIO1 and sRIO2
