ASoC: Blackfin: push down SPORT settings from global variables
Now that we have multi-component support, take the time to unify the
SPORT implementations a bit and make the setup dynamic. This kills
off the global sport_handle which was shared across all the Blackfin
machine drivers. The pin management aspect is off loaded to platform
resources, and now multiple SPORTs can be instantiated simultaneously.
