[Buildroot] [PATCH] package/linux-firmware: add WiFi and BT firmware for MT7920

Add firmware for the MediaTek MT7920 chip, which is handled by the
mt7921e driver. WiFi support was added in Linux 6.10 [1] and Bluetooth
support in Linux 6.9 [2]. The firmware files were added in [3] (WiFi)
and [4] (BT), included in linux-firmware since version 20241017.
