Ian Lepore b8bf08b1fa Add sdhci_handle_card_present_locked() that can be called from the interrupt
handler which already holds the mutex, and have sdhci_handle_card_present()
be just a tiny wrapper that does the locking for external callers.

This should fix the recursive locking panics seen on rpi3.
