soc: qcom: socinfo: separate major and minor format versions

The socinfo format version includes a 16-bit major field number
field that has always been zero, but may be changed in the future
to indicate a non-backwards-compatible format change. Update
current prints and checks to properly interpret both the major
and minor components.
