    sdhci: make isr tolerant of read errors
    The interrupt is shared with another device, which resumes earlier than the
    sdhci controller, and generates an interrupt.
    The sdhci interrupt handler runs, sees 0xffffffff in its own device's
    interrupt status, and tries to handle it..  The reason for the 0xffffffff
    is that the device is still suspended, and *all* regs are reading back
