ACPI: Introduce has_acpi_companion()
Now that the ACPI companions of devices are represented by pointers to struct fwnode_handle, it is not quite efficient to check whether or not an ACPI companion of a device is present by evaluating the ACPI_COMPANION() macro. For this reason, introduce a special static inline routine for that, has_acpi_companion(), and update the code to use it where applicable. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
