ASoC: wcd9335: Use int array instead of bitmask for TX mixers 

Currently slim_tx_mixer_get reports all TX mixers as enabled when
at least one is, due to it reading the entire tx_port_value bitmask
without testing the specific bit corresponding to a TX port.
Furthermore, using the same bitmask for all capture DAIs makes
setting one mixer affect them all. To prevent this, and since
the SLIM TX muxes effectively only connect to one of the mixers
at a time, turn tx_port_value into an int array storing the DAI
index each of the ports is connected to.
