[00/16] Add MediaTek IEEE 802.11ax devices - MT7915E

Message

MT7915E is the latest generation IEEE 802.11ax NIC in MediaTek, which
currently supports AP, Station and Mesh mode.

Even though some Tx/Rx paths of MT7915 [1] are similar to MT7615. Considering it
has huge amounts of HE parts, different designs of firmware, and most importantly,
for the sake of convenience to get family devices supported in the future, it was
concluded to be simpler to have a clean start for this generation.

This makes maintenance easier and avoids major changes in MT7615, which currently
shares the codes with low power capable device MT7663. It will increase the risk
of regressions in existing flow.

MT7915 supports only basic HE_SU for the mmoment, whereas other 802.11ax specific
features, such as BSS color, TWT, SR, DCM and OFDMA are WIP, and will be gradually
added in upcoming days.

The three firmwares are available from https://github.com/ryderlee1110/wireless-fw
they will be submitted soon. At last, the developers are all listed in the series.
