Managed to recover the I2C device by fully power-cycling the host.
Rebooting the Bluefield-2 card doesn't have an effect, issuing a reboot
through mlxconfig doesn't help either.
Confirmed that running "ipmitool mc info" is enough to test the
correctness of the patch, following again the result of the command run
on the Bluefield-2 machine:

Title:
i2c-mlxbf: Replace SAUCE patches with upstream content
Status in linux-bluefield package in Ubuntu:
New
Status in linux-bluefield source package in Jammy:
New
Bug description:
[Impact]
The BlueField I2C driver in Jammy and Noble repos consists of several SAUCE
patches.
There are now equivalent upstream patches that should be used instead.
[Fix]
* Revert SAUCE patches and then cherry-pick upstream patches that implement
the same functionality
* Include missing patches that were added upstream
[Test Case]
* Verify MLXBF I2C driver builds and loads without errors on Bluefield 2 and
Bluefield 3.
* Verify I2C block read of a device that requires repeated start conditions
succeeds using the following command: "i2cget -y <bus> <target> <reg> i
<bytes>".
* Verify IPMB communication with BMC to regression test general I2C behavior.
Used the following command which will result in several I2C transactions:
"ipmitool mc info".
[Regression Potential]
Low potential, as upstream commits have been tested and vetted by
upstream maintainers.
