Ma Ke 7f470524dc 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().

Fixes: 5b16a790f1 ("phy: cadence-torrent: Reorder few functions to remove function declarations")
