wireless: define cipher/AKM suites using a macro
The spec writes cipher/AKM suites as something like 00-0F-AC:9, but the part after the colon isn't hex, it's decimal, so that we've already had a few mistakes (in other code, or unmerged patches) to e.g. write 0x000FAC10 instead of 0x000FAC0A. Use a macro to avoid that problem. Reviewed-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
