sm8350-common: gps: Reorder initializations list to satisfy warnings

-Wreorder-ctor is a compile-time, Clang-only flag which is enabled by
default since Clang 12, which will warn whenever a specified field will
be initialized right after field specified below it. However, since it
doesn't sweep through all fields, compiler may miss some of them.

This order has been checked thoroughly through many trial and errors to
ensure that no such warns will be triggered anymore.
