Subject: mt76: Use the correct hweight8() function
Forwarded: https://marc.info/?l=linux-wireless&m=154998579614180&w=2
mt76_init_stream_cap() and mt76_get_txpower() call __sw_hweight8()
directly, but that's only defined if CONFIG_GENERIC_HWEIGHT is
enabled. The function that works on all architectures is hweight8().
Fixes: 551e1ef4d291 ("mt76: add mt76_init_stream_cap routine")
Fixes: 9313faacbb4e ("mt76: move mt76x02_get_txpower to mt76 core")
Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
[bwh: For 4.19, drop change in mt76_get_txpower()]
