machine: add the F7008-2.5 (GPOE-V1.2) 8+1 target

Add support for the F7008-2.5 board (PCB F7008-2.5GPOE-V1.2), an
RTL8373N + RTL8224N design with eight 2.5GBASE-T ports and one SFP+ cage.

The LED pads are not wired in port order, so the generic DEFAULT_8C_1SFP
target lights the wrong lamp on this board. The pad to lamp map was
measured on the hardware and is documented in doc/devices/F7008-2.5.md.

The green lamp marks a 2.5G link, the yellow lamp blinks while data flows.

+# F7008-2.5
+
+Documentation for the unmanaged 8 + 1 switch sold as `7018-2.5G` by Guangnianwei
+(光年微), board marking `F7008-2.5`, PCB `F7008-2.5GPOE-V1.2`.
+
+### Brands
+
+| Brand | Type | Managed | PCB | Flash | Chip RTL |
+|-------|------|---------|-----|-------|----------|
+| Guangnianwei (光年微) | 7018-2.5G | No | F7008-2.5GPOE-V1.2 | W25Q64JVSSIQ | 8373N + 8224N |
+
+### What works
+
+- All eight 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps
+- SFP+ port with 1G/2.5G/10G modules
+- LEDs of the eight RJ45 ports
+
+### Not verified
+
+- The LED pads for the SFP+ cage are not mapped yet. The SFP+ lamps are left
+  undriven, so an inserted module lights nothing.
+- The UART header footprint is present but unpopulated, and no boot log could be
+  captured from it, so the baud rate is unknown. There are most likely
+  unpopulated 0-Ohm resistors next to the header; bridging those should bring
+  the console to life.
+
+### Build target
+
+```
+make MACHINE=F7008_2_5
+```
+
+### LED wiring
+
+Measured pad to lamp map (`led_mux` index -> lamp):
+
+| Port | green lamp | yellow lamp |
+|------|-----------|-------------|
+| 1 | pad 0  | pad 1  |
+| 2 | pad 2  | pad 3  |
+| 3 | pad 4  | pad 5  |
+| 4 | pad 6  | pad 8  |
+| 5 | pad 9  | pad 10 |
+| 6 | pad 12 | pad 15 |
+| 7 | pad 18 | pad 21 |
+| 8 | pad 24 | pad 25 |
+
+Pads 7, 11, 13, 14, 16, 17, 19, 20, 22, 23, 26 and 27 do not drive an RJ45 lamp.
+
+The front panel is silkscreened `2.5G: Green / 10/100M: Yellow`, and the target
+follows it: the green lamp is on while the port is linked at 2.5G, the yellow
+lamp blinks while data is flowing.
+
+### PCB overview
+
+The board is marked `F7008-2.5GPOE-V1.2`.

+- 4 x `RT4802SNE` magnetics
+- Unpopulated UART header footprint, next to the magnetics
+- Power input 12V 1A, 180 x 84 x 29 mm metal case
