mvebu: add support for Check Point V-80

Check Point V-80 (Quantum Spark 1550 Appliance) is an Appliance, based
on Armada 7040 (88F7040).

Specification:

- SoC             : Marvell Armada 7040 (88F7040)
- RAM             : DDR4 2 GiB (4x Nanya NT5AD512M8D3-HR)
- Flash           : eMMC 4 GiB (Toshiba THGBMNG5D1LBAIL)
- Ethernet        : 6x 10/100/1000 Mbps
  - LAN 1-5       : Marvell 88E6352
  - WAN           : Marvell 88E1512
- LEDs/Keys (GPIO): 6x/1x
- UART            : "CONSOLE" port (USB 1.1 Type-C)
  - chip          : Silicon Labs CP210x
  - port          : ttyS0
  - settings      : 115200bps 8n1
- HW Monitoring   : 2x nuvoTon NCT7802Y
- USB             : USB 3.0 Type-A
- Power           : 12 VDC, 3.3 A
  - plug          : DC Plug 2.5/5.5 mm (inner/outer)

Flash instruction (common):

1. Boot V-80 normally
2. Login to the vendor CLI (default: admin/admin) and login to the Linux
   CLI by `expert` command
3. Update U-Boot environment variables by the following commands

   fw_setenv bootcmd_ow_usb 'usb start; load usb 0:1 ${loadaddr} boot.scr && source ${loadaddr}'
   fw_setenv bootcmd_ow_emmc 'run set_mmc_internal; mmc read ${loadaddr} ${prim_header_mmc_blk} 4 && source ${loadaddr}'
   fw_setenv bootcmd 'set cp_quiet; run set_bootargs_vx; run bootcmd_ow_usb; run bootcmd_ow_emmc; run bootcmd_part${activePartition};'

   Attention: don't forget single quatations of values to prevent
              expansion of variables

4. Turn off the device

Flash instruction (USB-boot):

1. Burn (squashfs|ext4)-usb.img.gz to USB storage
2. Connect that storage to the USB 3.0 port on V-80
3. Turn on V-80 and it will be booted with OpenWrt in that USB storage

Flash instruction (eMMC-boot):

1. Copy initramfs image, dtb and bootsctipt to the USB storage with
   renaming

   initramfs.bin -------> Image
   dtb -----------------> armada-7040-v-80.dtb
   bootscript (.scr) ---> boot.scr

2. Connect that storage to the USB 3.0 port on V-80
3. Turn on V-80 and it will be booted with OpenWrt initramfs image in
   that USB storage
4. Upload (squashfs|ext4)-sysupgrade.gz to V-80
5. Perform sysupgrade with the uploaded image
6. Wait ~100 seconds to complete flashing

Reverting to stock firmware:

1. Turn on V-80 and interrupt booting by Ctrl + C
2. Select "4. Restore to Factory Defaults (local)"
3. Wait ~180 seconds to complete restoring and rebooting

Notes:

- V-80 has some HW versions. Internal MicroSD card slot and mPCIe slot
  is available on some HW versions, but not on the other HW versions.

  confirmed (MicroSD/mPCIe slots):

  - 1.0.1: unavailable
  - 1.0.3: available

- The partition table in the internal eMMC has single partition, but
  "blkdevparts=" parameter will be passed from the bootloader and that
  definition will be used instead.

MAC addresses:

LAN: 00:1C:7F:xx:xx:4B (mmcblk1boot0, ethaddr (text))
WAN: 00:1C:7F:xx:xx:4A (mmcblk1boot0, eth1addr (text))
