The type-specific "create" routines that get called while parsing
the descriptor entries in the module manifest assume the size they
are provided is the size of their data portion only--not including
the descriptor header.
Compute this value in greybus_new_module(), and pass it to those
functions rather than the full descriptor size. Move a few
declarations to the innermost block that uses them.

When interpreting a manifest descriptor header, don't assume there
is enough space in the buffer to hold a descriptor header. Also,
verify the remaining buffer is at least as big as the reported
descriptor size.

The type field in a manifest descriptor header is in little endian
format. Make sure we interpret it that way.

As soon as we've called device_initialize() we're required to call
put_device() in order to drop our reference to the device structure.
This was missed in the error path in greybus_new_module(). Fix that.

Define a structure that describes the entire greybus manifest.
Adjust greybus_new_module() to use that, making it explicit that
it's not just a header that's being provided to that function.

We agreed to rename a few things to improve clarity. This patch
implements one of those changes. The blob of data that describes
what's relevant to Greybus within an Ara module will now be called
the "module manifest." In addition, in the context of Greybus we'll
also be calling what's in an Ara module a "module" or "Greybus module."
So this patch renames some structures and updates some comments. It
also renames "greybus_desc.h" to be "greybus_manifest.h", and renames
greybus_new_device() to be greybus_new_module().
