soc: qcom: pil: Extend minidump ToC logs for auxiliary entries 



Currently, only the main subsystem ToC is printed during
SSR minidump collection, but the ToC for the auxiliary
entries are not, which makes it difficult to debug issues
with the ToC for the auxiliary entries.

Add logging to print out the minidump ToC for a subsystem's
auxiliary entries.
