Subject: [PATCH] mt76: mt7615: fix mt7615 firmware path definitions

mt7615 patch/n9/cr4 firmwares are available in mediatek folder in linux-firmware repository. Because of this mt7615 won't work on regular distributions like Ubuntu. Fix path definitions. Moreover remove useless firmware name pointers and use definitions directly

Fixes 04b8e65922f6 ("mt76: add mac80211 driver for MT7615 PCIe-based chipsets")
