[PATCH] Fixing SD response type 6 vs. 1

[PATCH] Fixing SD response type 6 vs. 1

[Ragner Magalhaes]

From: Ragner Magalhaes <ragner.magalhaes@indt.org.br>

Fixing reponse type R6 for CMD3 when SD Card will be attached.

Ignoring OMAP_MMC_STAT_CARD_ERR, treating it as if the command
completed correctly.
