2021-10-20mt76: mt7915: change max rx len limit of hw modulesShayne Chen
Update max rx len of some hw modules, which aligns out vendor SDK. In normal modes, we exchange MPDU 7991 cap with peers; however, this won't play a part in sniffer mode. To prevent packets which exceed the max MPDU size from entering specific rx path in hw, we need to set a proper limit to filter them out.

2021-10-20mt76: mt7915: enable HE UL MU-MIMOShayne Chen
Enable HE UL MU-MIMO in sta_rec_muru, which works on both ap and station mode. For sending trigger frames, one of the conditions fw uses is to check if mib rx airtime meets the threshold. There's a main control of mib rx airtime report register in fw, so we need to enable the register by mcu cmd instead of directly writing it, otherwise it will still be disabled by fw.

2021-10-20mt76: mt7915: fix hwmon temp sensor mem use-after-freeBen Greear
Without this change, garbage is seen in the hwmon name and sensors output for mt7915 is garbled. It appears that the hwmon logic does not make a copy of the incoming string, but instead just copies a char* and expects it to never go away.
