ath5k: update dependencies

- Use config symbol defined in the driver instead of arch specific one for
  conditional compilation.
- Rename the ATHEROS_AR231X config symbol to ATH25.
- Fix include (ar231x_platform.h -> ath25_platform.h).
- Some of AR231x SoCs (e.g. AR2315) have PCI bus support, so remove !PCI
  dependency, which block AHB support build.
