[atheros]: Add initial kernel 2.6.28 support for atheros target. The include files moved from /include/asm-mips/mach-atheros/ to /arch/mips/include/asm/mach-atheros/ This patch is based on the old kernel 2.6.27 patches. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@14584 3c298f89-4303-0410-b956-a3cf2f4a3e73
