mt7615: mcu: do not use function pointers whenever possible
Remove function pointers in mt7615_mcu_set_bss_info and run function directly. Moreover remove __mt7615_mcu_set_bss_info since it is run just by mt7615_mcu_set_bss_info and remove duplicated istructions Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
