The 'dsp' node is currently configured for running an audio firmware.
Since the firmware requires that some audio-related IPs be disabled in
Linux, this will clash with the configurations from the imx8 board DTs
(i.e: imx8qm-mek, imx8qxp-mek, etc...), thus making the dsp unusable
(since the firmware won't function properly).
To avoid this issue, configure the 'dsp' node for rproc. This way, users
will be able to use the dsp alongside the board-level audio configuration
as long as the firmware doesn't need the audio IPs.

Add Toradex Verdin Ivy carrier board support. One notable feature of Ivy
is the analog inputs. These inputs are multiplexed, allowing the same
input to measure either voltage or current. For current measurements,
a GPIO switch enables or disables the shunt resistor. This process is
automatically managed by the Linux kernel using the IIO and MUX
subsystems. Voltage measurement is always enabled, but the voltage
measured by the ADC is scaled by a cascade voltage divider. In the
device tree, the equivalent gain of the voltage divider is used, which
can be calculated as follows:
