x86: Set default baud rate on Geode images to 115200
Prior to commit 1496b95a0 ("x86: clean up default grub baudrate
settings") we had three different baud rates for the Geode targets:
19200 for net5501, 38400 for alix2, and 115200 for Geos.
It doesn't seem that there's a very good reason for varying from our
default 115200 baud, so let's make the Geode target do that instead.
