Hi Jani,
This patch uses the simplified fallback logic where
if link train fails, we first lower the max sink link rate
to a lower value until it reaches RBR keeping the max lane count
unchanged and then lower the lane count and set max lane count to
this lowered lane count and resetting the link
If link training fails, then we need to fallback to lower
link rate first and if link training fails at RBR, then
fallback to lower lane count.
This function finds the next lower link rate/lane count
value after link training failure and limits the max
link_rate and lane_count values to these fallb
