ath5k: Remove AHB bus support

AHB bus support was added in v2.6.38, through commit a0b907e ("ath5k: Add AHB bus support."). That code can only be build if the Kconfig symbol ATHEROS_AR231X is set. But that symbol has never been added to the tree. So AHB bus support has always been dead code. Let's remove all code that depends on ATHEROS_AR231X. If that symbol ever gets added to the tree the AHB bus support can be re-added too. Signed-off-by: Paul Bolle <[email protected]> Signed-off-by: John W. Linville <[email protected]>
