iio: dac: Convert powerdown read callbacks to sysfs_emit()
Update DAC drivers powerdown attribute show callback to use the new
sysfs_emit() function.
sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it
knows about the sysfs buffer specifics and has some built-in sanity checks.
