Lars-Peter Clausen f46ac00978 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.
