docs/regmap/adi_regmap_dac.txt : Updated and added some registers
-Updated description of some fields of these registers: REG_CHAN_CNTRL_1, REG_CHAN_CNTRL_2, REG_CHAN_CNTRL_3, REG_CHAN_CNTRL_4, REG_USR_CNTRL_4, and REG_USR_CNTRL_5 -Added two new registers, both with their own fields and description: REG_CHAN_CNTRL_9 and REG_CHAN_CNTRL_10 Signed-off-by: Cristian Mihai Popa <cristianmihai.popa@analog.com>main
