[SRU][F:linux-bluefield][PATCH v2 0/1] UBUNTU: SAUCE: bluefield_edac: Add SMC support

[Shravan Kumar Ramani]

BugLink: https://bugs.launchpad.net/ubuntu/+source/linux-bluefield/+bug/1916318

SRU Justification:

[Impact]
Since secure calls have been enabled for bluefield_edac via ACPI and the driver
does not currently support them, all EMI register reads will return 0,
and writes will have no effect.
So the edac driver will not provide any valid logs when an ECC error occurs.

[Fix]
Add support for SMC in bluefield_edac.

[Test case]
Verified by injecting an ECC error to trigger an EDAC event.
The driver logs display information from EMI registers accessed via secure calls.
