Ma Ke 6516149e03 phy: cadence-torrent: Check return value on register read

[ Upstream commit 967969cf59 ]

cdns_torrent_dp_set_power_state() does not consider that ret might be
overwritten. Add return value check of regmap_read_poll_timeout() after
register read in cdns_torrent_dp_set_power_state().
