Title:
  mmc: sdhci-of-dwcmshc: Intermittent data error under stress test

Status in linux-bluefield package in Ubuntu:
  Invalid
Status in linux-bluefield source package in Jammy:
  Fix Committed

Bug description:
  sdhci-dwcmshc MLNXBF30:00: __mmc_blk_ioctl_cmd: data error -110

  SRU Justification:

  [Impact]
  This change is needed to avoid intermittent "sdhci-dwcmshc MLNXBF30:00: 
__mmc_blk_ioctl_cmd: data error -110" error under stress test

  [Fix]
  The fix added a quirk for the BF3 sdhci driver to avoid such data error.

  [Test Case]
  1. Same functionality and testing as on BlueField-1/2.
  2. Install OS on NVME, and run the FIO test on EMMC.
  fio --name=mmcblk0_randrw_stress_round_1 \
    --ioengine=libaio --direct=1  --time_based=1 \
    --end_fsync=1 --ramp_time=5 --norandommap=1 \
    --randrepeat=0 --group_reporting=1 --numjobs=8 \
    --iodepth=128 --rw=randrw --overwrite=1 \
    --runtime=3600 --bs=4K --filename=/dev/mmcblk0 &

  
  [Regression Potential]
  Same behavior from user perspective.
