iio: adc: adi-axi-adc: only error out in major version mismatch
[ Upstream commit cf1c833f89e7c8635a28c3db15c68ead150ea712 ]
The IP core only has breaking changes when there major version changes.
Hence, only match the major number. This is also in line with the other
core ADI has upstream. The current check for erroring out
'expected_version > current_version"' is then wrong as we could just
increase the core major with breaking changes and that would go
unnoticed.
