ASoC: qcom: sc8280xp: use sa8775p/ subdir for QCS9100 / QCS9075

All firmware for the Lemans platform aka QCS9100 aka QCS9075 is for
historical reasons located in the qcom/sa8775p/ subdir inside
linux-firmware. The only exceptions to this rule are audio topology
files. While it's not too late, change the subdir to point to the
sa8775p/ subdir, so that all firmware for that platform is present at
the same location.
