[OpenWrt-Devel] [RFC 2/3] ath25: factor out Fonera 2.0g kernel options

[Sergey Ryazanov]

Disable SoCs and PCI options in the common ath25 kernel config and
enable required options on per-subtarget basis. E.g. generic config
activates all SoCs but keeps PCI support disabled, and fon2202 config
activates only AR2315 but with the PCI support.
