Support added for transmission of CMD23 during multi block read or
write. In order to activate this feature, MMC_CAP_CMD23 flag needs
to be enabled in the capabilities field. Note that CMD23 support is
mandatory to support features like reliable write, data tag, context

Tegra30 differs from Tegra20 in a number of ways. This patch implements a
minimal set of differences in order to get the Cardhu board's SD slot and
eMMC working. Given the diffs between the mainline sdhci-tegra.c and our
downstream versions, I expect we'll eventually need to add many more

This patch groups the read or write transfers to eMMC in different contexts
based on the block number. Transfers to consecutive blocks are grouped to a
common context. So several small transfers combine to give performance like
a large multi block transfer.

Found this issue during code review. Actually, there are two
issues which both compensate together in lucky case.
In unlucky case the bus width probing might not work as expected.

Block interrupts give interrupt on completion of every LLI, which is actually
too much interrupts. This is just not required for current functioning of

So, just don't handle them at all.
