Fix printf warnings

This fixes five warnings like:

hardware/akm/AK8975_FS/libsensors/AkmSensor.cpp:143:44: warning: format
specifies type 'long long' but the argument has type 'int64_t' (aka
'long')

Also reformat a tiny bit of immediately surrounding code.

Bug: None
Test: mma. Warnings are gone.
