Subject: [PATCH] mt76: mt7615: introduce mt7615_eeprom_parse_hw_band_cap routine
Git-commit: b3d95f0968919d4859051c7cd2129bc1b30d2fe9
Patch-mainline: v5.7-rc1
References: jsc#SLE-13430

Introduce mt7615_eeprom_parse_hw_band_cap routine in order to configure
supported band for mt7663e and mt7622 devices since they do not rely on
eeprom data to enable 2GHz/5GHz bands
