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.
