[PATCH 0/5] iio: adc: xilinx-xadc: Add I2C interface support for System Management Wizard

[Sai Krishna Potthuri <sai.krishna.potthuri@amd.com>]

The existing driver only supported AXI memory-mapped access to the System
Management Wizard IP. This series extends the driver to support I2C-based
access, which is particularly useful for System Controller usecases.

Key Changes:
- Extract common probe logic into xadc_device_setup() and
xadc_device_configure().
- Add setup_channels function pointer to ops structure to support
different ways to configure the channels.
- Replace module_platform_driver() macro with custom init and exit
functions to support multiple bus interfaces.
- I2C interface support.
- Convert binding file to YAML format.

Note: We are working on x86 platform support where fixed channel
configuration is used(no DT support). The setup_channels function
pointer introduced in patch 2/3 enables different channel configuration
approaches for various platforms.
