LSM6DSO i2c handle buf

[dyldonahue]

Observed Behavior

I saw this quickly and am not positive I’m not going crazy @Sabramz please confirm.

The i2c handle pointer in mpu.c (hardcoded to be used In lsm6dso static inline funcs) does not seem to actually ever be initialized and will be a nullptr

Expected Behavior

In the MSB FW implementation of lam6dso wrapper functions, the i2c device is grabbed via extern. (Not a ptr). Code was verified there and it’s a lost simpler. Let’s change this so that it gets the Correct i2c device via extern

Steps to Reproduce
