[yocto] [meta-raspberrypi][PATCH 2/5] linux-raspberrypi: Set baudrate and use serial0 for kgdboc

The driver for 8250 defaults to 9600. We setup it on 115200 to be consistent
with getty configuration.

The firmware can do its magic with kgdboc too as it searches and replaces
=serial0 and =serial1. So, use serial0 for kgdboc too.
