Add compat-wireless recipe.

This recipe was based on the compat-wireless.inc recipe from openembedded-classic
  at commit 53784a5e2622582ce5e2ffb91bbdb573503ed75e

The .inc is there in order to make it possible to have such recipes:
  $ cat compat-wireless-ath_0.bb
  include compat-wireless.inc

  do_configure() {
  	cd ${S}
          ./scripts/driver-select ath
  }

0001-ath5k-fix-compilation-without-CONFIG_PCI.patch will have to be submitted upstream
