mt76x0: do not overwrite other MT_BBP(AGC, 8) fields

Browse source

commit b983a5b900 upstream.

MT_BBP(AGC, 8) register has values depend on band in
mt76x0_bbp_switch_tab, so we should not overwrite other fields
than MT_BBP_AGC_GAIN when setting gain.

This can fix performance issues when connecting to 2.4GHz AP.
