iio: dac: ad3552r: change AD3552R_NUM_CH define name
After model data and num_hw_channles introduction, we have:
ad3552r_desc, num_ch: used to keep channel number set in fdt,
ad35xxr_model_data, num_hw_channels: for max channel checks,
AD3552R_NUM_CH: just actually used to define the max array size
on allocated arrays.
Renaming AD3552R_NUM_CH to a more consistent name, as AD3552R_MAX_CH.
