ACPI / LPSS: Support for device latency tolerance PM QoS
Add a new routine, acpi_lpss_set_ltr(), for setting latency tolerance values for LPSS devices having LTR (Latency Tolerance Reporting) registers. Add .bind()/.unbind() callbacks to lpss_handler to set the LPSS devices' power.set_latency_tolerance callback pointers to acpi_lpss_set_ltr() during device addition and to clear them on device removal, respectively. That will cause the device latency tolerance PM QoS to work for the devices in question as documented. This changeset includes a fix from Mika Westerberg. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
