Add the power domains names to the power domain struct so we
have meaningful name for every power domain. This also removes the
following debugfs error message.
[ 2.242068] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present!
[ 2.249949] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present!
[ 2.257784] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present!
