dt-bindings: soc: qcom: qcom,saw2: add missing compatible strings

Define compatible strings for SAW2 units present on MSM8960, IPQ4019
and IPQ8064.  There is no need to include SAW version into the compat
string, so just use the SoC and SAW2 kind.

Also add missing L2 SAW2 compatibles for MSM8974 and APQ8084, they
follow the existing CPU SAW2 strings.
