[PATCH 1/3] printk: provide generic dynamic_hex_dump fallback

The lack of a silent fallback for this routine has caused the nfit driver and the virtio_rpmsg_bus to develop local workarounds. Define a nop version of dynamic_hex_dump() in the CONFIG_DYNAMIC_DEBUG=n case so we can clean up those local workarounds.
