OpenWrt support for Linksys MX4200

[sppmaster]

Look here, the things have changed since the time you haven't followed the development.

Here’s the updated mapping:

NSS Branch	Upstream Branch	Notes
24.10-nss	openwrt-24.10
main-nss	main	Renamed from qualcommax-6.x-nss-wifi

EDIT: Same logic is applied to the MX4300 supported branch qualcommax-6.x-nss-mx4300 -> 24.10-nss-mx4300 , and main-nss-mx4300 .
