arm64: tegra: Disable CQE Support for SDMMC4 on Tegra186
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.
