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.
