The Seeed Xiao NRF52840 Kit's default GPS is an L76K which operates at 9600 baud, so when this variant was defined that baud rate was specified. However, this is a development board and it is expected that users can attach their own devices. This includes GPS, which may operate at a different baud rate. The current fixed baud rate prevents this, so this patch removes that setting. This will revert to the regular automatic probe method. This will sucessfully detect the L76K as before (probably the same as before since 9600 baud is the first baud rate checked), but also allow other GPSes at other baud rates to be detected.
