Cleanup for Air530z GPS

[fifieldt]

It turns out that the Air530z is a GNSS_MODEL_MTK. Our existing code detects and configures it properly. This patch removes a couple of AIROHA ifdefs since they are not required for a working GPS.

@fifieldt This change also affects Tracker T1000-e GPS

yes @markbirss , I believe setting #define GPS_BAUDRATE 115200 in the T1000e variant.h is incorrect: the Air530z defaults to 9600. Try removing that line?

Does not seem to help.

What's breaking? What is it detecting as? Can you confirm if the Air530 in the T1000E is the same as the Air530 available for sale from the Seeed store (I.e. an Air530z)?

I cannot confirm only have T1000-E

@Dylanliacc can you confirm ?

[fifieldt]

Thanks for looking at it. If it's not too much trouble, what are the baud rates it tries?

[markbirss]

It does try couple 9600,4800, 57600 and 115200 but still fails
