In the sdhci_request function, the card is determined to be present based
on the SDCD pin status. SDHCI host controllers that do not use SDCD pin
but rely on other mechanism such as external pin interrupts, update the
host flags with SDHCI_DEVICE_DEAD flag based on the card insertion status.
This patch modifies the sdhci_request function such that the it uses
both the SDCD status and SDHCI_DEVICE_DEAD host flag to determine if the
card is inserted or not.
