dt-bindings: iio: hmc425a: add conditional GPIO array size constraints
ADRF5740 and HMC540S have a 4 bit parallel interface.
Update ctrl-gpios description and min/maxItems values depending on the
matched compatible to correctly reflect the hardware properties.
Fixes: 79f2ff6461e7 ("dt-bindings: iio: hmc425a: add entry for ADRF5740 Attenuator")
Fixes: 20f87a9a26be ("dt-bindings: iio: hmc425a: add entry for HMC540S")
