SRU Justification:

[Impact]

Sync up the ipmb_dev_int.c with the latest version available in the upstream master branch.

[Fix]

* cherry-pick fc26067c7417e7fafed7bcc97bda155d91988734
  ipmi: remove open coded version of SMBus block write
* pull changes from commit 0924c5a0cbed5831a2a0ff2f9a19692265f1ab92
  The above commit makes modifications to 3 files:
  ipmb_dev_int.c, ipmi_ipmb.c and ipmi_ssif.c
  ipmi_ipmb.c doesn't exist on 5.4, so we just pull the change from ipmb_dev_int.c

[Test Case]

* check ipmb_dev_int is loaded without failure (check dmesg and lsmod)
* verify that /dev/ipmb-2 is created
* run ipmi command from bmc to send requests to BF DPU and verify that the response is as expected

[Regression Potential]

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