Subject: [PATCH] mt76: mt76u: introduce mt76u_alloc_mcu_queue utility routine
Git-commit: 94e1cfa890b74ee37ea80af76da704775b202b4b
Patch-mainline: v5.7-rc1
References: jsc#SLE-13430
Add mt76u_alloc_mcu_queue utility routine to allocate mcu hw rx queue.
This is a preliminary patch to support new devices (e.g. mt7663u) that
rely on a hw queue for mcu messages
