ASoC: intel: sof_sdw: Clean up DAI link counting

The counting of each of the types of DAI link is a bit messy with things
added onto an intermediate variable as it goes along. Re-order things a
little to keep the order consistent with the rest of the function and
simplify the process down to a variable for each type of DAI and then
sum them at the end.
