[PATCH v3 8/8] mmc: dw_mmc: fix the checking whether card is present

[Jaehoon Chung <jh80.chung@samsung.com>]

Broken card detection is assumed "the card is present".
Non-removable card didn't call get_cd().
dw-mmc controller didn't check whether card is present or not.
Because DW_MMC_CARD_PRESENT flag is set into dw_mci_get_cd().
If cd-pin is used, then dw_mci_get_cd() is called.
