[OpenWrt-Devel] [PATCHv5] ramips: add support for SamKnows SK-WB8

Hopefully third time's the charm:

PATCHv1:
This patch adds support for the SamKnows version 8.0 Whitebox, built
around the MT7621 platform. 2.4GHz appears to be working, albeit
poorly; 5GHz not working yet.

PATCHv2:
Fixed LED name in DTS.

PATCHv3:
 DTS: Syntax error fixed, LEDs and buttons mapped correctly now
- diag.sh updated to blink WPS LED on boot
- 2.4GHz wifi is working but txpower is stuck at 0, DTS ROM offset
matches SamKnows firmware
- 5GHz wifi not working, DTS pcie1,0 matches SamKnows firmware

PATCHv4:
- I didn't commit some fixes in PATCHv3, that's fixed now

PATCHv5:
- Added preinit hook to reset SamKnows Whitebox 8 u-boot boot counter
to prevent soft brick by booting into nonexistent backup partition
- Broke 2.4GHz WiFi but 5GHz sorta works (swapped pcie0/1 in DTS,
needs further investigation, effective txpower is still 0)
- Experimenting on wifi but that'll be a future patch, board boots fine now.
