Subject: [PATCH] mmc: sdhci-omap: Fix busy detection by enabling
 MMC_CAP_NEED_RSP_BUSY

It has turned out that the sdhci-omap controller requires the R1B response,
for commands that has this response associated with them. So, converting
from an R1B to an R1 response for a CMD6 for example, leads to problems
with the HW busy detection support.

Fix this by informing the mmc core about the requirement, via setting the
host cap, MMC_CAP_NEED_RSP_BUSY.
