ARM: mm: proc-mohawk: Use the new processor struct macros
This patch also defines a suitable flush_icache_all implementation which would otherwise be missing, resulting in a link failure. Thanks to Nicolas Pitre for suggesting the code for this. Signed-off-by: Dave Martin <dave.martin@linaro.org> Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
