Make Ublox code more readable (#4727)

* Simplify Ublox code

Ublox comes in a myriad of versions and settings. Presently our
configuration code does a lot of branching based on versions being
or not being present.

This patch adds version detection earlier in the piece and branches
on the set gnssModel instead to create separate setup methods for Ublox 6,
Ublox 7/8/9, and Ublox10.

Additionally, adds a macro to make the code much shorter and more
readable.
