Tested with 100 times boot tests on dra71x-evm, dra72x-evm and dra7xx-evm. v3: Removed the command error specific callback and using the already existing sdhci_irq callback instead. No measurable drop in performance. v2: Added EXPORT_SYMBOL_GPL for sdhci_cmd_err and sdhci_send_command to fix errors when built as module.
