ACPI / scan: constify first argument of struct acpi_scan_handler::match
One wouldn't expect a "match" function modify the string it searches
for, and indeed the only instance of the struct
acpi_scan_handler::match callback, acpi_pnp_match, can easily be
changed. While there, update its helper matching_id().
This is also preparation for constifying struct acpi_hardware_id::id.
