qca-ssdk: pass SoC to build

Recent SSDK versions started also parsing the "SoC" variable to identify
the SoC along with the "CHIP_TYPE".

We are not passing "SoC" currently and this leads to components we dont
need like MHT (New 2.5G quad port switch) being compiled and then unused,
so lets just pass the "SoC" as well.
