This patch support the driver model for s5p_sdhci controller.
To support the legacy model, maintained the existing code.
Note: If use the Driver Model, it needs to modify the device-tree.
In future, will update the Device-tree and enable the configuratioin.

By default saveenv option is not supported for SPL. This patch
enable the support for save environment variable for SPL build.
Enable save environment support in SPL after setenv. By default
the saveenv option is not provided in SPL, but some boards need
this support in 'Falcon' boot, where SPL need to boot from
different images based on environment variable set by OS. For
example OS may set "reboot_image" environment variable to
"recovery" inorder to boot recovery image by SPL. The SPL read
"reboot_image" and act accordingly and change the reboot_image
to default mode using setenv and save the environemnt.

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
struct tegra_mmc_priv to make its purpose more obvious. The new name is
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
they'll be deleted by a subsequent patch in this series.

The MMC driver will soon be converted to use standard clock/reset APIs,
and so the periph_id field in the MMC device priv struct will disappear.
Rework the implementation of pad_init_mmc() to rely on this; using the
device register address is a much more direct test anyway.

The Tegra MMC driver currently honors "sdhci" entries in /aliases. The
MMC core however uses "mmc" entries in /aliases. This difference will be
relevant once the Tegra MMC driver is converted to DM, and the MMC core
handles alias lookups. To avoid issues during that conversion, fix the
Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC
core does.

Some code may want to read reg values from DT, but from nodes that aren't
associated with DM devices, so using dev_get_addr_index() isn't
appropriate. In this case, fdtdec_get_addr_size_*() are the functions to

nodes) may still be desirable. Add a function parameter to request that,
