PM / Domains: Mark "name" const in dev_pm_domain_attach_by_name()
As of the patch ("PM / Domains: Mark "name" const in genpd_dev_pm_attach_by_name()") it's clear that the name in dev_pm_domain_attach_by_name() can be const. Mark it as so. This allows drivers to pass in a name that was declared "const" in a driver.
