Update the driver to parse the new unified bus-width property introduced
in commit 7f21779 "mmc: dt: Consolidate DT bindings", instead of the legacy
support-8bit property.

Chris, It's probably easiest conflict-wise if I take this through the Tegra
tree. (Note: When I posted this series before, I said there shouldn't be any
conflicts if you take them through the MMC tree. That's probably still true,
but unforseen future conflicts seem more likely in the .dts files in the
second patch than sdhci-tegra.c in this patch, so the Tegra tree may make
more sense). Since the second patch depends on the first, it's easiest if
these go in through the same tree. Does this sound OK?
