Andre Brait 1d5e4cd722 doc: identify the Horaco SWTG118AS-V2.1 CPU and flash capacity
Read register 0x0004 on all three tested HC-SWTGW218AS units. Each returned 0x83730000, identifying RTL8373 rather than RTL8373N. Firmware reports 2 MB flash on all three.

Fill in the verified device-table fields and document the non-N/N register distinction. Leave PHY and flash-chip models explicitly unverified.

### ZX-SWTGW218AS
## Brands
|Brand|Type|Managed|PCB|Flash|Chip RTL|
|---|---|---|---|---|---|
| Mokerlink | ZX-SWTGW218AS | Yes| SWTG118AS-V2.0-16029 | 2MB (FM25Q16A)| 8273N + 8224N |
| Sodola | | | | | |
| Horaco | HC-SWTGW218AS | Yes | SWTG118AS-V2.1 | 2MB | 8373 (non-N) |
| XikeStor | SKS3200-8E1X | Yes | SWTG118AS-V2.1-17462 | 2MB (25Q16JVSIQ) | |
All boards in this table use `MACHINE=SWTGW218AS`. The Horaco HC-SWTGW218AS is also sold with the
[SWTG018AS-A V2.0](SWTG018AS_A_V2_0.md) board, which needs a different firmware. Check the marking
on the PCB before flashing.
On all three tested Horaco HC-SWTGW218AS units with PCB SWTG118AS-V2.1, `regget 4` returned
`REGGET: 0x0004: VAL: 0x83730000`, identifying the CPU as RTL8373 (non-N). An RTL8373N returns
`0x83737000` instead. The PHY and flash-chip models on these units have not been verified.
