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.
