Tuan Phan b1d2d3dd01 ACPI/IORT: Fix PMCG node single ID mapping handling 
[ Upstream commit 50c8ab8d9fbf5b18d5162a797ca26568afc0af1a ]

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.

Fixes: 24e516049360 ("ACPI/IORT: Add support for PMCG")
