Buswidth is depeneded on Hardware schematic.
Evne though host can support the 8bit buswidth, if hardware doesn't
support 8bit mode, it doesn't work fine.
So the buswidth mode selection leaves a matter in each SoC drivers.
On the contrary to this, hardware supports 8bit mode, but host doesn't
support it. then controller has to disable the MMC_MODE_8BIT.
(Host can check whether 8bit mode is supported or not, since V3.0)

Currently, CONFIG_MMC is not related to any other options by
"depends on" or "select". One of big advantages of using Kconfig
is automatic dependency tracking, but the current state is lacking
it. As the first step, make the existing MMC driver entries depend
on MMC.

struct mmc_host is a Tegra-specific structure, but the name implies it's
something defined by core MMC code, which is confusing. Rename it to

also more appropriate for a DM driver private data structure, which will
be relevant later in this series.
Nothing needs access to this type except the MMC driver itself. Move the
definition into the driver C file.
Make sure all Tegra MMC functions are named tegra_mmc_*. Even though
they're all static, it's useful to have good naming so that symbol tables
are easy to interpret. A few functions aren't renamed by this patch since

The Tegra MMC driver currently honors "sdhci" entries in /aliases. The

core does.
