The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

There are a large number of options under CONFIG_SYS (but some of these
are elsewhere, spotted while cleaning CONFIG_SYS) that are never
referenced, or only used slightly later in the config file.  Remove or
restructure these.

- Ensure that everyone setting mtdids= and mtdparts= is doing so via the
  CONFIG options.
- If the CONFIG options are set, ensure that the default environment
  sets mtdparts / mtdids.

The "autoload" environment variable is always checked with env_get_yesno
as it can be set to any form of no.  The default behavior of
env_get_yesno is to return -1 on variables that are not set, which acts
as true in general (we test for non-zero return).  To convert
CONFIG_SYS_AUTOLOAD to Kconfig, given that it was almost always used to
set autoload to no, first rename to CONFIG_SYS_DISABLE_AUTOLOAD for
consistency sake.  Then, make it so that if enabled we set autoload=0 in
the default environment.  Migrate all platforms which set
CONFIG_SYS_AUTOLOAD to non-true or that set autoload to false in their
default environment to using CONFIG_SYS_DISABLE_AUTOLOAD
