Add initial support for the IEI Puzzle-M801 1U Rackmount Network
Appliance board.

The board is based on the quad-core Marvell Armada 8040 SoC and supports
up to 16 GB of DDR4 2400 MHz ECC RAM. It has a PCIe x16 slot (x2 lanes
only) and an M.2 type B slot.

Main system hardware:
2x USB 3.0
4x Gigabit Ethernet
2x SFP+
1x SATA 3.0
1x M.2 type B
1x RJ45 UART
1x SPI flash
1x IEI WT61P803 PUZZLE Microcontroller
1x EPSON RX8010 RTC (used instead of the integrated Marvell RTC controller)
6x SFP+ LED
1x HDD LED

All of the hardware listed above is supported and tested in this port.

Changes for v2:
- Use the correct vendor title (IEI instead of iEi)
- Sync the device tree with dt-bindings

This patch is now sent separately from the IEI WT61P803 PUZZLE MCU
patchset. Go to the following link for reference:
