cd4462326c atheros: v3.18: cleanup register headers
AFAIK, no one AR2315+ chip (AR2315, AR2316, AR2317, AR2318) does not
contain IR block, so remove IR registers definitions. Also remove few
unused macroses.

fa097e5ae5 kernel: disbale HAMRADIO in generic config
HAMRADIO enabled in all generic configs, but no one platform directly
use related drivers/protocols. This symbol is only used for kmod-ax25
package modules. Furthermore, half of platforms explicitly disables
this symbol, what silently disables build of modules for kmod-ax25
package.

So disable HAMRADIO by-default in generic config, add it to kmod-ax25
package and remove it from platform specific configs.

Explicitly configure PCI host controller, and do not expose it to PCI
