[SRU][J:linux-bluefield][PATCH v2 0/6] bluefield_edac: replace SAUCE patches with upstream content

[David Thompson]

BugLink: https://bugs.launchpad.net/bugs/2085561

SRU Justification:

[Impact]
The BlueField-1/BlueField-2 EDAC driver in Jammy repo consists of several SAUCE patches.
There are now equivalent upstream patches that should be used instead.

[Fix]
1) Revert the three SAUCE patches for bluefield_edac driver
2) Cherry pick four upstream patches for bluefield_edac driver

[Test Case]

1) Boot BlueField-2 with relevant software

2) Check initial state of correctable error count, should be 0
  $ cat /sys/devices/system/edac/mc/mc0/ce_count

3) Find sysfs entry for DRAM ECC injection
  $ find / -name 'DRAM_ECC_INJECT'

4) Inject ECC error
  $ echo 1 > OUTPUT-FROM-STEP3-ABOVE

5) Repeat step 4 until this error message appears on console
    "ERROR: BL31: MSS0 EMEM MI Single bit ECC detected"

6) Check new state of correctable error count, should be non-zero
  $ cat /sys/devices/system/edac/mc/mc0/ce_count

[Regression Potential]
Low potential, as upstream commits have been tested and vetted by upstream maintainers.
