Remove GPS Baudrate locking for Seeed Xiao NRF52840 Kit (#7016)

Browse Source 
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.
