mmc: sdhci: disable MMC_CAP_NEEDS_POLL in nonremovable case

When a controller requires SDHCI_QUIRK_BROKEN_CARD_DETECTION, we poll
for card insertion/removal, and that creates interrupts.  There's no
need to be doing this if we have a non-removable card.

This patch requires cards to be removable before we're willing to set
MMC_CAP_NEEDS_POLL.
