An IORT PMCG node can have no ID mapping if its overflow interrupt is wire based therefore the code that parses the PMCG node can not assume the node will always have a single mapping present at index 0. Fix iort_get_id_mapping_index() by checking for an overflow interrupt and mapping count.

I understand we are very late in the cycle but I wanted to ask (it applies cleanly to for-next/acpi).
Sorry, Lorenzo -- I didn't notice that this had been Acked already. I was waiting for somebody to chime in! I'll queue it ASAP for 5.8.
