perf: qcom_l2_pmu: Refactor _UID handling to use acpi_dev_uid_to_integer()
ACPI utils provide acpi_dev_uid_to_integer() helper to extract _UID as an integer. Use it instead of custom approach. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
