Add support for AG3352 and fix AG3335 support

Browse Source 
AG33352 is a Mediatek/Airoha GPS/GLONASS/Galileo/BeiDou receiver.
Patch adds relevant detection and setup code.

Thanks to Bluebrolly and kongduino for providing the relevant
information and testing.

This patch also fixes support for the A3335, which is a related chip.
The setup and detection code now works as tested on a real life
T-1000E!

Thanks to @gpsfan for the guidance.
