7683092632 dt-bindings: iio: dac: ad3552r: add iio backend support 
There is a version of AXI DAC IP block (for FPGAs) that provides
a physical QSPI bus for AD3552R and similar chips, so supporting
spi-controller functionalities.

For this case, the binding is modified to include some additional
properties.

0fbce5d171 dt-bindings: iio: dac: fix ad3552r gain parameter names 
The adi,gain-scaling-p/n values are an inverted log2,
so initial naming was set correctly, but the driver uses just
adi,gain-scaling-p/n, and if fdt is created accordingly with
the fdt bindings documentation, driver fails the probe.

Observing that:
- the Linux driver is the only consumer,
- there are no upstreamed dts nodes related to ad3552r,

the fix to the documentation side is preferred and less-risk.
