Enabling CQE support on Tegra186 Jetson TX2 has introduced a regression
that is causing accesses to the file-system on the eMMC to fail. Errors
such as the following have been observed ...
mmc2: running CQE recovery
mmc2: mmc_select_hs400 failed, error -110
print_req_error: I/O error, dev mmcblk2, sector 8 flags 80700
mmc2: cqhci: CQE failed to exit halt state
For now disable CQE support for Tegra186 until this issue is resolved.

Hi ARM SoC maintainers,
Turned out there was a hardware bug that currently prevents CQE from
working on Tegra186. Patches for this are being worked on and are on
track to be merged for v5.2 but they are too involved to make it into
v5.1, so let's back out CQE support on Tegra186.
Can you please apply this for v5.1-rc3?
Thanks,
Thierry
