hikey: turn on printk.devkmsg for 4.9 kernel

With 4.9 kernel, ratelimit is default for kernel messages,
so we would not see message printed from userspace like following:
    init: starting service 'surfaceflinger'...

The information like this is necessary for us to know the status of android boot
during development, so turn on printk.devkmsg from the boot parameters.

kernel documentation is here:
https://android.googlesource.com/kernel/hikey-linaro/+/android-hikey-linaro-4.9/Documentation/kernel-parameters.txt#3273

Test: manually with hikey
