db845c: Set baud rate for serial console

The default baud rate on kernel releases prior to v5.10
is 9600, which breaks serial console for db845c and AOSP
takes a loooooong time to boot.

Upstream resets default baud rate to 115200 in commit
2ec812a04ff4 ("tty: serial: qcom_geni_serial: 115.2 is a
better console default than 9600").

Fixes: a0d7e989f159 ("Enable serial console on dragonboard devices.")
