SRU Justification:

[Impact]

OCP3.0 project was discontinued and canceled so all stale code related to
that was removed.
The HID MLNXBF29 is used now for triggering a graceful shutdown for the Bobcat
board. On the bobcat board, the main board cpld issues the shutdown request to
the dpu cpld. the dpu cpld issues that request to ARM via GPIO6 and ARM should
trigger a graceful shutdown and set the ARM boot progress to 6.

[Fix]

The HID MLNXBF29 is used now for triggering a graceful shutdown for the Bobcat
board. On the bobcat board, the main board cpld issues the shutdown request to
the dpu cpld. the dpu cpld issues that request to ARM via GPIO6 and ARM should
trigger a graceful shutdown and set the ARM boot progress to 6.

[Test Case]

* Test shutdown on Bobcat via CPLD command.

[Regression Potential]

* no known regression as the OCP3.0 board was discontinued.
