This patch adds card detection setup to SDHCI platform data on SMDK2416. It was not tested because I don't have access to SMDK2416 board anymore, but I tested similar patch on another board.

Note: it depends on patches:

ARM: S3C24XX: Fix gpiolib support for ports K..M
ARM: S3C2416: Add clock definition for HSMMC1
ARM: S3C2416: Add platform helpers for setup SDHCI
Samsung: sdhci-s3c: add support for new card detection methods
sdhci-s3c: add support for the non standard minimal clock value
sdhci-s3c: add support for new card detection methods

PATCH 1/1 ARM: S3C2416: Add support of SD/MMC card detect on SMDK2416

Enable card detect by GPIO pin on hsmmc1 device (SD0 on SMDK2416 board) and enable card polling on hsmmc0 (SD1).
