Commit 316ca880 ("ACPI/IORT: Remove linker section for IORT entries
probing") removed the linker section for IORT entries probing.

Since those IORT entries were the only iort_node_match() interface
users, the iort_node_match() became obsolete and can then be removed.

Remove the ACPI IORT iort_node_match() interface from the kernel.
