Regenerate defconfig files ...

Update defconfig files with the following script.

for a in arch/*; do
	arch=$(basename $a)
	for c in $a/configs/*; do
		config=$(basename $c)

	export ARCH=$arch
	make $config && make savedefconfig && mv defconfig $c
	done
done

arch: refresh defconfigs ...

The defconfig files are long untouched and a
make xy_defconfig; make savedefconfig usually generates quite
a different looking file. Refresh them to make it easier to generate
patches against the configs using
make xy_defconfig; make menuconfig; make savedefconfig

This has been done with the following script.

for a in arch/*; do
	arch=$(basename $a)
	for c in $a/configs/*; do
		config=$(basename $c)

	export ARCH=$arch
	make $config && make savedefconfig && mv defconfig $c
	done
done

defaultenv: add defaultenv-1 in boards via defaultenv_append_directory() ...

Currently it's hardcoded for each board which defaultenv version is
used. This is unfortunate since some people like the other defaultenv
version better and may want to select it.

This patch removes the board specific environment path
CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via:

	if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC))
		defaultenv_append_directory(defaultenv_<board>);

This way we can make sure that the defaultenv-1 board specific bits are
only compiled in when defaultenv-1 is actually in use.

The next step is to make the defaultenv version selection a user visible
choice.

bootm: Move bootm options to common/Kconfig ...

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

This will allow to have hw driver or asm optimised driver.

Use a priority level to determine which one to use at runtime.
The generic one will be 0.

defenv: remove bogus defaultenv from defconfigs ...

When CONFIG_DEFAULT_ENVIRONMENT_GENERIC is set the Make system
will automatically compile in defaultenv/ into the environment. Some
boards explicitely add this path again in their defconfig which is
not needed. Remove it.
