[PATCH 11/12] mfd: twl4030-irq: Return twl6030_mmc_card_detect IRQ for board setup

[Benoit Cousson <b-cousson@xxxxxx>]

Card detect IRQ from the TWL6030 used to be provided to the MMC
controller code using a statically allocated IRQ scheme:

  card_detect_irq = TWL6030_IRQ_BASE + MMCDETECT_INTR_OFFSET;

This is no longer valid in a SPARSE_IRQ context since there is no more
pre-defined TWL6030_IRQ_BASE.

Return the proper card detect IRQ value in the twl6030_mmc_card_detect_config
that will be called from the MMC controller.
