sdhci: Split card-detection IRQs management from sdhci_init()
Card detection interrupts should be handled separately as they should not be enabled before mmc_add_host() returns and should be disabled before calling mmc_remove_host(). The same is for suspend and resume routines. sdhci_init() no longer enables card-detection irqs. Instead, two new functions implemented: sdhci_enable_card_detection() and sdhci_disable_card_detection(). New sdhci_reinit() call implemented to behave the same way as the old sdhci_init(). Also, this patch implements and uses few new helpers to manage IRQs in a more conveinient way, that is: - sdhci_clear_set_irqs() - sdhci_unmask_irqs() - sdhci_mask_irqs() - SDHCI_INT_ALL_MASK constant sdhci_enable_sdio_irq() converted to these new helpers, plus the helpers will be used by the subsequent patches.
