iio: dac: ltc2632: Fix formatting in kerneldoc struct header

Kerneldoc expects attributes/parameters to be in '@*.: ' format.

Fixes the following W=1 kernel build warning(s):

 drivers/iio/dac/ltc2632.c:50: warning: Function parameter or member 'powerdown_cache_mask' not described in 'ltc2632_state'
 drivers/iio/dac/ltc2632.c:50: warning: Function parameter or member 'vref_mv' not described in 'ltc2632_state'
 drivers/iio/dac/ltc2632.c:50: warning: Function parameter or member 'vref_reg' not described in 'ltc2632_state'
