[U-Boot] [PATCH 00/30] env: Move environment code to use location drivers

The environment code is ripe for improvement in various ways. It has lots
of duplication and inconsistencies between how things work with different
environment locations. It does not properly use Kconfig. Error checking
and handling is patchy.

This series makes a start at improving things:

- moves the rest of the CONFIG_ENV_IS_IN_... options to Kconfig
- introduces the concept of a location driver for the environment
- drops some of the duplicated code
- improves error handling a little (more to be done here)
- moves code into a new env/ directory

There is still much more to do:
- complete Kconfig conversion (e.g. CONFIG_ENV_SIZE)
- unify environment settings so that all locations support the same options
- try to rationalise the redundancy code (can we create a common
    implementation used by all drivers?)
- allow environment in multiple locations (e.g. as a fallback)
- figure out why CONFIG_ENV_IS_IN_FLASH enables the environment in flash
    even in SPL, which other locations do not
