Subject: [PATCH] mt76: mt76u: introduce mt76u_free_rx_queue utility routine
Git-commit: 38e09a49f449e77849a271f1457489d1932b7182
Patch-mainline: v5.7-rc1
References: jsc#SLE-13430

Introduce mt76u_free_rx_queue utility routine to free rx hw queue.
This is a preliminary patch to support new devices (e.g. mt7663u) that
rely on a hw queue for mcu messages
