net: sfp: rework the RollBall PHY waiting code
RollBall SFP modules allow the access to PHY registers only after a
certain time has passed. Until then, the registers read 0xffff.
Currently we have quirks for modules where we need to wait either 25
seconds or 4 seconds, but recently I got hands on another module where
the wait is even shorter.
Instead of hardcoding different wait times, lets rework the code:
- increase the PHY retry count to 25
- when RollBall module is detected, increase the PHY retry time from
50ms to 1s
