iio: dac: ad3530r: Convert sw_ldac_trig_reg to a function pointer

Browse source

The software LDAC trigger register is stored in the chip_info table as a
fixed register address. Devices with a multi-bank register architecture
select the trigger register based on the channel being updated, which a
single static address cannot express.

Convert sw_ldac_trig_reg into a function pointer that returns the
trigger register for a given channel, mirroring the input_ch_reg
callback.
