Add support for TP-Link AX53

[frollic]

Using an older kernel and a QSDK, not Openwrt, it doesn't help at all.

Add OpenWrt support for Redmi AX3000 (256MB RAM) Wi-Fi 6 Mesh Router?

No, that device is not supported and in all likeliness 'never' supportable. ipq50xx is not supported at this point, so far no one is working in this SoC either. 256 MB RAM is a hard no-go for 2* ath11k radios, even 512 MB are tight, very tight.
