[PATCH 2/2] iio: dac: ad3530r: add support for AD3536R

[Kim Seer Paller]

The AD3536R is the 12-bit variant of the AD3532R, a 16-channel buffered
voltage output DAC with an on-chip 2.5V reference and an identical
register map. Add a chip_info entry for it and the corresponding SPI and
OF device ID table entries.
