kernel: add KERNEL_DEVMEM and KERNEL_DEVKMEM
These options are needed to create /dev/mem or /dev/kmem . /dev/mem is needed by the io tool to access raw hardware memory, which is helpful when debugging and developing drivers. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Acked-by: John Crispin <john@phrozen.org>
