Kim Seer Paller 1131e70558 iio: dac: ad3530r: Fix incorrect masking for channels 4-7 in powerdown mode 
In the current implementation of ad3530r_set_dac_powerdown() function,
the macro AD3530R_OP_MODE_CHAN_MSK(chan->channel) is used to generate
the bitmask for the operating mode of a specific channel. However, this
macro does not account for channels 4-7, which map to the second
register AD3530R_OUTPUT_OPERATING_MODE_1 for the 8 channeled device. As
a result, the bitmask is incorrectly calculated for these channels,
leading to improper configuration of the powerdown mode. Resolve this
issue by adjusting the channel index for channels 4-7 by subtracting 4
before applying the macro. This ensures that the correct bitmask is
generated for the second register.
