Frostflow: Always initialize retimer when enabled
The A1 retimer will be enabled anytime the board boots. Ensure
that the tuning parameters are applied every time the retimer is enabled
again since they clear when the retimer is disabled.
BUG=b:273849234,b:280957965
TEST=on frostflow, run suspend stress test and verify retimer
initialization always reports success talking to the chip, spot check
tuning register contents
