My CD pin is not available at all (DW_MCI_QUIRK_BROKEN_CARD_DETECTION is
set). The result was in v3.12 that if MMC card was inserted at load
time, then the MMC card was detected. If it wasn't, it wasn't detected
since nobody polled for it and I no irq was wired up.
I haven't noticed any change in that area, therefore I'm adding the
MMC_CAP_NEEDS_POLL flag in case the detection is broken so the core will
check for the MMC card.
