Subject: [PATCH 5/8] phy: cadence-torrent: register resets even if the phy
 is already configured

Resets are needed during suspend and resume stages.
So they shall be registered during the probe even the phy is already
initialized.

The function cdns_torrent_reset is renamed cdns_torrent_of_get_reset() to
make it clear.
