Replace fip_create with fiptool 

fiptool provides a more consistent and intuitive interface compared to
the fip_create program.  It serves as a better base to build on more
features in the future.

fiptool supports various subcommands.  Below are the currently
supported subcommands:

1) info   - List the images contained in a FIP file.
2) create - Create a new FIP file with the given images.
3) update - Update an existing FIP with the given images.
4) unpack - Extract a selected set or all the images from a FIP file.
5) remove - Remove images from a FIP file.  This is a new command that
   was not present in fip_create.

To create a new FIP file, replace "fip_create" with "fiptool create".

To update a FIP file, replace "fip_create" with "fiptool update".

To dump the contents of a FIP file, replace "fip_create --dump" with
"fiptool info".

A compatibility script that emulates the basic functionality of
fip_create is provided.  Existing scripts might or might not work with
the compatibility script.  Users are strongly encouraged to migrate to
fiptool.

./tools/fiptool/fiptool info <path-to>/fip.bin
Example 3: update the entries of an existing Firmware package:

# Images will be unpacked to the working directory
./tools/fip_create/fip_create --unpack <path-to>/fip.bin

Example 5: remove an entry from an existing Firmware package:
./tools/fiptool/fiptool remove \

Note that if the destination FIP file exists, the create, update and
remove operations will automatically overwrite it.
The unpack operation will fail if the images already exist at the
destination. In that case, use -f or --force to continue.
More information about FIP can be found in the [Firmware Design document]
[Firmware Design].
#### Migrating from fip_create to fiptool
The previous version of fiptool was called fip_create. A compatibility script

However, users are strongly encouraged to migrate to fiptool.
* To create a new FIP file, replace "fip_create" with "fiptool create".
