PM / Domains: Add power-on function using names to identify domains
It sometimes is necessary to turn on a given PM domain when only the name of it is known and the domain pointer is not readily available. For this reason, add a new helper function, pm_genpd_name_poweron(), allowing the caller to turn on a PM domain using its name for identification. To avoid code duplication, move the domain lookup code to a separate function. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
