iio: imu: inv_mpu6050: make arrays hz and d static
Don't populate the arrays on the stack, instead make them static.
Makes the object code smaller by 135 bytes:
Before:
text data bss dec hex filename
15135 4240 128 19503 4c2f inv_mpu_core.o
After:
text data bss dec hex filename
14840 4400 128 19368 4ba8 inv_mpu_core.o
