qoriq: add support for NXP T4240RDB board

Hardware specs:
  - NXP T4240, 12C/24T @ 1.67 GHz
  - 3 × 2 GB DDR3 SO-DIMM
  - 128 MB NOR flash
  - 2 GB SLC NAND
  - SD card interface
  - PCIe: x4 and x8
  - SATA 3 Gbps
  - 8 × 1 GbE
  - 4 × 10 GbE SFP
  - RTC

This commit adds the sysupgrade and factory images for T4240RDB board in
both variants:
  - nor: for booting and read whole system from NOR memory
  - sdboot: for booting and read whole system from SD card

SD Card images install:

  - Burn image to sdcard. E.g:
      gunzip -c gunzip -c openwrt-qoriq-generic-fsl_T4240RDB-squashfs-sdcard.img.gz | \
      sudo dd of=/dev/mmcblk0 conv=fsync,notrunc status=progress bs=4M && sync
  - Download lastest Cortina PHY firmware from NXP github [1], if you accept their
    EULA [2].
  - Install Cortina PHY on image, E.g:
      dd if=cs4315-cs4340-PHY-ucode.txt of=/dev/mmcblk0 bs=1 seek=2M
  - Insert SD-Card to SD slot
  - Switch SW3.4 to OFF
  - Configre mac addresses from sticker in u-boot. E.g:
      setenv ethaddr 00:10:f3:3a:a8:66
      setenv eth1addr 00:10:f3:3a:a8:67
      setenv eth2addr 00:10:f3:3a:a8:68
      setenv eth3addr 00:10:f3:3a:a8:69
      setenv eth4addr 00:10:f3:3a:a8:6a
      setenv eth5addr 00:10:f3:3a:a8:6b
      setenv eth6addr 00:10:f3:3a:a8:6c
      setenv eth7addr 00:10:f3:3a:a8:6d
      setenv eth8addr 00:10:f3:3a:a8:6e
      setenv eth9addr 00:10:f3:3a:a8:6f
      setenv eth10addr 00:10:f3:3a:a8:70
      setenv eth11addr 00:10:f3:3a:a8:71
      saveenv
  - reset and boot

NOR images install:

  - download and extract factory image on tftp server root
  - boot device and stop in u-boot (from nor or sd card u-boot)
  - configure server and ip address. E.g:
      setenv ipaddr 192.168.1.2
      setenv serverip 192.168.1.1
  - Download image and run flashing:
      tftpboot $loadaddr openwrt-qoriq-generic-fsl_T4240RDB-squashfs-factory-nor.bin
      protect off all
      erase $fwaddr +$filesize
      cp.b $loadaddr $fwaddr $filesize
  - Switch SW3.4 to ON
  - Switch SW3.1-3 to OFF
  - reboot
  - Do postprocessing (see bellow)

NOR images post processing:

  - Configre mac addresses from sticker in u-boot. E.g:
      setenv ethaddr 00:10:f3:3a:a8:66
      setenv eth1addr 00:10:f3:3a:a8:67
      setenv eth2addr 00:10:f3:3a:a8:68
      setenv eth3addr 00:10:f3:3a:a8:69
      setenv eth4addr 00:10:f3:3a:a8:6a
      setenv eth5addr 00:10:f3:3a:a8:6b
      setenv eth6addr 00:10:f3:3a:a8:6c
      setenv eth7addr 00:10:f3:3a:a8:6d
      setenv eth8addr 00:10:f3:3a:a8:6e
      setenv eth9addr 00:10:f3:3a:a8:6f
      setenv eth10addr 00:10:f3:3a:a8:70
      setenv eth11addr 00:10:f3:3a:a8:71
      saveenv
  - boot
  - Download and refresh RCW stored in eeprom:
      tr '\0' '\377' < /dev/zero | dd bs=256 of=/sys/bus/i2c/devices/0-0050/eeprom
      cat /tmp/openwrt-qoriq-generic-fsl_T4240RDB-squashfs-rcw.bin > /sys/bus/i2c/devices/0-0050/eeprom
  - Download lastest Cortina PHY firmware from NXP github [1], if you accept their
    EULA [2].
  - Install Cortina PHY on image, E.g:
      mtd write cs4315-cs4340-PHY-ucode.txt /dev/mtd4
  - reset and boot
