Powerpc/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 P5020 board. So add quirk
SDHCI_QUIRK2_LONG_TIME_CMD_COMPLETE_IRQ to enlarge this detect time to avoid
hardware timeout error.
