iio: max9611: Use sysfs_emit() 



sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it
knows about the sysfs buffer specifics and has some built-in checks for
size and alignment.

Use sysfs_emit() to format the custom `in_power_shunt_resistor` and
`in_current_shunt_resistor` device attributes of the max9611 driver.
