[SRU][F:linux-bluefield][PATCH v1 0/1] UBUNTU: SAUCE: Add ipmb_host.c driver

[Asmaa Mnebhi]

Buglink: https://bugs.launchpad.net/bugs/1980532

SRU Justification:

[Fix]

* In 5.4 and our internal repos we need to support the ipmb_host.c driver which allows sending IPMB request from the BF DPU to the BMC.

[Test Case]

* check that ipmb_host.c driver is loaded at boot time and with no errors
* lsmod
* check that the /dev/ipmi0 device file is created successfully
* Please note that this driver (like other host IPMI drivers), depends on ippmi_msghandler.c and ipmi_devint.c. They have to be loaded for ipmb_host.c to be loaded successfully
* send ipmi commands from the BF DPU to the BMC and make sure the response is as expected.

[Regression Potential]

Any of the test cases above could be impacted due to these changes.
