Do not perform phy/vga calibration during channel switch. Moreover remove mt76x0_agc_save and mt76x0_agc_restore routines since they are no longer necessary. Furthermore run mt76_set_channel in order to check if there are pending frames during channel switch Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
