For example to store the environment in a file named "/uboot.env" in MMC
"0", where partition "1" contains the EXT4 filesystem, the following
configs should be added to the board's default config:
CONFIG_ENV_IS_IN_EXT4=y
CONFIG_ENV_EXT4_DEVICE_AND_PART="0:1"
CONFIG_ENV_EXT4_FILE="/uboot.env"
CONFIG_ENV_EXT4_INTERFACE="mmc"

With the change to the environment code to remove the common init stage
of pointing to the default environment and setting it as valid, combined
with the change to switch gd->env_valid from 0/1/2 to an enum we now
must set env_valid to one of the enum values rather than an int. And in
this case, not only was setting it to an int wrong, it was now the wrong
value. Finally, in the case of ENV_IS_NOWHERE we must still say that
our envionrment is invalid after init for things to continue to
function.

Changes in v3:
- Actually include changes for env/nowhere.c
Use the env_save() function directly now that there is only one
implementation of saveenv().

This is a strange name for a function that loads the environment. There is
now only one implementation of this function, so use the new env_load()
function directly instead.

We only have a single implementation of this function now and it is called
env_get_char(). Drop the old function and the weak version.

Now that env_init() is only defined once we can drop the env_init_new()
name and just use env_init().

declared by each driver.

Most of the init() implementations just use the default environment.
Adjust env_init_new() to do this automatically, and drop the redundant
code.

We plan to move to a environment access via drivers for each location
where the environment can be stored. Add an implementation for this. So
far it is not used, but will be pressed into service in a future patch.
