Modified Files:
        src/sys/dev/marvell: mvsdio.c

Log Message:
Add check during mvsdio_attach that CMD line is in idle state.

If the CMD line is not in idle state, the interrupt handler routine will
misbehave causing an endless interrupt handler loop.  This would prevent
the the kernel from getting to mountroot.

On my Pogoplug POGO-V4-A3-01, this was caused by U-Boot routing com1's TX
and RX signals to the SD card slot's CMD and DAT[0] lines respectively.

We should probably grow Marvell SoC MPP (pinmux) configuration frobs.
