kernel: kmod-ramoops: Include pstore console support

Browse Source 
Pstore ramoops support is useful even when there isn't an explicit
panic/crash. We can log all kernel messages via a "console", and then
retrieve them in the event of some non-kernel-panic reset (e.g.,
watchdog).

Since the buffer memory is already reserved, there isn't much overhead
to doing this.

The new console files will show up as:

  /sys/fs/pstore/console-ramoops-N
