powerpc/t1023rdb: Add T1023 RDB board support

T1023RDB is a Freescale Reference Design Board that hosts the T1023 SoC.

T1023RDB board Overview
-----------------------
- T1023 SoC integrating two 64-bit e5500 cores up to 1.4GHz
- CoreNet fabric supporting coherent and noncoherent transactions with
  prioritization and bandwidth allocation
- Memory: 2GB Micron MT40A512M8HX unbuffered 32-bit fixed DDR4 without ECC
- Accelerator: DPAA components consist of FMan, BMan, QMan, DCE and SEC
- Ethernet interfaces:
  - one 1G RGMII port on-board(RTL8211F PHY)
  - one 1G SGMII port on-board(RTL8211F PHY)
  - one 2.5G SGMII port on-board(AQR105 PHY)
- PCIe: Two Mini-PCIe connectors on-board.
- SerDes: 4 lanes up to 10.3125GHz
- NOR:  128MB S29GL01GS110TFIV10 Spansion NOR Flash
- NAND: 512MB S34MS04G200BFI000 Spansion NAND Flash
- eSPI: 64MB S25FL512SAGMFI010 Spansion SPI flash.
- USB: one Type-A USB 2.0 port with internal PHY
- eSDHC: support SD/MMC card and eMMC on-board
- 256Kbit M24256 I2C EEPROM
- RTC: Real-time clock DS1339 on I2C bus
- UART: one serial port on-board with RJ45 connector
- Debugging: JTAG/COP for T1023 debugging

As well updated T1024RDB to add T1023RDB.
