ath79: add kernel 5.10 support
This adds Kernel 5.10 support for the generic, nand and tiny subtargets.
The following patch is not contained, as it needs to be reworked:
platform/920-mikrotik-rb4xx.patch
Tested-on:
- Siemens WS-AP3610
- Enterasys WS-AP3710
- Aerohive HiveAP 121
- TP-Link TL-WA901 v2
- TP-Link TL-WR741 v1
