There are only a few things found in <mtd.h> today. Go through and audit
the C files which include <mtd.h> and remove it when not required. Then,
add it to the files which had either missed it or had an indirect
inclusion of it.

The FWU metadata access driver for MTD partitioned devices currently
uses a statically allocated array for storing the updatable image
information. This array depends on the number of banks and images per
bank. With migration of the FWU metadata to version 2, these
parameters are now obtained at runtime from the metadata.
Make changes to the FWU metadata access driver for MTD devices to
allocate memory for the image information dynamically in the driver's
probe function, after having obtained the number of banks and images
per bank by reading the metadata. Move the image information as part
of the driver's private structure, instead of using a global variable.

In version 2 of the metadata structure, the size of the structure
cannot be determined statically at build time. The structure is now
broken into the top level structure which contains a field indicating
the total size of the structure.
Add a size parameter to the metadata access API functions to indicate
the number of bytes to be accessed. This is then used to either read
the entire structure, or only the top level structure.

In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, on a separate
region. Add a driver for reading from and writing to the metadata
when the updatable images and the metadata are stored on a raw
MTD region.
The code is divided into core under drivers/fwu-mdata/ and some helper
functions clubbed together under lib/fwu_updates/
