servo_micro: Increase USART2 queue size
When servo_micro is forwarded to a remote machine with usbip
(go/chromeos-wfh-tools#usbip) and the FPMCU console is on USART2, I see
dropped characters:
> help
Known commands:
chan flashwrite gpioset reboot sysinfo
crash fpcapture hc history rw taskinfo
flashinfo e info; HELP CMD = help on CMD.
This doesn't happen when using the same setup with servo_micro's USART3,
which has a larger queue size of 1024, so increase USART2 queue size to
match.
