soc: qcom: socinfo: Add support for new fields in revision 20

Add support for socinfo version 20. Version 20 adds a new field
package id and its zeroth bit contain information that can be
can be used to tune temperature thresholds on devices which might
be able to withstand higher temperatures. Zeroth bit value 1 means
that its heat dissipation is better and more relaxed thermal
scheme can be put in place and 0 means a more aggressive scheme
may be needed.
