mmc/eSDHC: host need long time to generate command complete interrupt
According to Spec 2.0, command complete interrupt will be generate
within 150 SD-CLK. But this was not long enough for T1040 board.
So add quirk SDHCI_QUIRK2_LONG_TIME_CMD_COMPLETE_IRQ
to enlarge this detect time to avoid hardware timeout error.
