powerpc/t1024qds: Add T1024 QDS board support

T1024QDS is a high-performance computing evaluation, development and
test platform for T1024 QorIQ Power Architecture processor.

T1024QDS board Overview
-----------------------
- T1024 SoC integrating two 64-bit e5500 cores up to 1.4GHz
- CoreNet fabric supporting coherent and noncoherent transactions with
  prioritization and bandwidth allocation
- 32-/64-bit DDR3L/DDR4 SDRAM memory controller with ECC and interleaving support
- Accelerator: DPAA components consist of FMan, BMan, QMan, DCE and SEC
- Ethernet interfaces:
  - Two 10M/100M/1G RGMII ports on-board
  - Three 1G/2.5Gbps SGMII ports
  - Four 1Gbps QSGMII ports
  - one 10Gbps XFI or 10Base-KR interface
- SerDes: 4 lanes up to 10.3125GHz Supporting SGMII/QSGMII, XFI, PCIe, SATA and Aurora
- PCIe: Three PCI Express controllers with five PCIe slots.
- IFC: 128MB NOR Flash, 2GB NAND Flash, PromJet debug port and Qixis FPGA
- Video: DIU supports video up to 1280x1024x32 bpp.
  - Chrontel CH7201 for HDMI connection.
  - TI DS90C387R for direct LCD connection.
  - Raw (not encoded) video connector for testing or other encoders.
- QUICC Engine block
  - 32-bit RISC controller for flexible support of the communications peripherals
  - Serial DMA channel for receive and transmit on all serial channels
  - Two universal communication controllers, supporting TDM, HDLC, and UART
- Deep Sleep power implementaion (wakeup from GPIO/Timer/Ethernet/USB)
- eSPI: Three SPI flash devices.
- SATA: one SATA 2.O.
- USB: Two USB2.0 ports with internal PHY (one Type-A + one micro Type mini-AB)
- eSDHC: Support SD, SDHC, SDXC and MMC/eMMC.
- I2C: Four I2C controllers.
- UART: Two UART on board.
