iPod Classic: updates for uc8702 driver

Browse source 
- Small rework on the UC8702 UART controller to make it compatible with
  other s5l870x SOCs. Files moved and renamed, many conditional code
  added to deal with capabilities and 'features' of the different CPUs.

- A couple of optimizacions that should not affect the functionality.
