Add a new compatible and related bindings for the fpga-based
AD408x AXI IP core, a variant of the generic AXI ADC IP.
The AXI AD408x IP is a very similar HDL (fpga) variant of the
generic AXI ADC IP, intended to control ad408x familiy.
Although there are some particularities added for extended
control of the ad408x devices such as the filter configuration.
Wildcard naming is used to match the naming of the published
firmware.

Add a new compatible and related bindings for the fpga-based
AD485x AXI IP core, a variant of the generic AXI ADC IP.
The AXI AD485x IP is a very similar HDL (fpga) variant of the

Although this is not preferred, the wildcard naming is used to
match the published firmware under the same name.

A new compatible is added to reflect the specialized version of the HDL.
We use the parallel interface to write the ADC's registers, and
accessing this interface requires to use ADI_AXI_REG_CONFIG_RD,
ADI_AXI_REG_CONFIG_WR and ADI_AXI_REG_CONFIG_CTRL in a custom fashion.

Add a required clock property as we can't access the device registers if
the AXI bus clock is not properly enabled.
Note this clock is a very fundamental one that is typically enabled
pretty early during boot. Independently of that, we should really rely on
it to be enabled.

'adi,adc-dev' is now deprecated and must not be used anymore. Hence,
also remove it from being required.
The reason why it's being deprecated is because the axi-adc CORE is now
an IIO service provider hardware (IIO backends) for consumers to make use
of. Before, the logic with 'adi,adc-dev' was the opposite (it was kind
of consumer referencing other nodes/devices) and that proved to be wrong
and to not scale.
Now, IIO consumers of this hardware are expected to reference it using the
io-backends property. Hence, the new '#io-backend-cells' is being added
so the device is easily identified as a provider.
