So far mtd partitions were mtd devices, but these were not registered.
This patch changes this. mtd partitions are now registered like real
mtd devices. This makes them part of the device hierarchy.

struct mtd_info contains members which should not be copied
to the new partition, like for example the class_dev, so
only copy selected members of struct mtd_info to the partition.

mtd->parent is optional so we can't derefence mtd->parent->device_node
without checking mtd->parent.

erase_info may be modified by the mtd partition code, so
set the address each time we call mtd_erase.

This adds a target to generate environment files from directories.
These are compiled into the barebox binary.
use it as:
bbenv-$(CONFIG_SOMETHING) += my-environment
The directory containing the files to compile into the binary
should be named my-environment.
This can be accessed in C code later as:
extern unsigned char __bbenv_my_environment_start[];
extern unsigned char __bbenv_my_environment_end[];

The default environment buffer is an unsigned char array and thus
may be unaligned. Some decompression algorithms expect the buffer
to be sufficiently aligned for u32 accesses. We make this sure by
copying the default env to a temporary buffer. Instead of doing this
just add a __aligned(4) to the default environment.

Instead of asking explicitly for the default environment compression
type ask for the in-barebox default compression type. This also adds
a DEFAULT_COMPRESSION_SUFFIX make variable which can be used together
with the wildcard rules for compressed files to generate compressed
files without explicitly support each compression type.

Finding out whether to rebuild the environment is a difficult task
since we have to track all files in a directory. Instead of trying
this, just rebuild the environment during every build and only if
it differs to the last one overwrite the target. This way make
only sees a change when the environment is changed.
