ath79: fix several issues for ZyXEL NBG6716

This fixes several issues introduced with ZyXEL NBG6716 support:
- Inhomogeneous indent
- Wrong ath10k MAC patching function
- Wrong brackets for pad-to in nand.mk
- Add missing DEVICE_MODEL
- Remove k2t.sh include (copy/paste leftover)

Fixes: 99835e0999 ("ath79: add support for ZyXEL NBG6716")
