mmc: sdhci_am654: Workaround for Errata i2312
Errata i2312 [0] for K3 silicon mentions the maximum obtainable
timeout through MMC host controller is 700ms. And for commands taking
longer than 700ms, hardware timeout should be disabled and software
timeout should be used.
The workaround for Errata i2312 can be achieved by adding
SDHCI_QUIRK2_DISABLE_HW_TIMEOUT quirk in sdhci_am654.
