build: Default to use TI degenerate key for signing on non-HS devices

Switch to using the TI degenerate key to sign the system firmware binary
image on GP devices during the image tree blob build process. Using this
key speeds up the time needed by the ROM code execution for processing
this image and with this shortens our boot time.

The previous default behavior of signing with a random key can still
be triggered by passing an empty KEY variable to the make command as

$ make KEY=""

Introduce framework to build SYSFW and config data into an ITB

In order to be able to consume system firmware (SYSFW) as well as the
associated configuration data from the boot media introduce a framework
that allows building the SYSFW image itself as well as the different
domain-specific configuration fragments (board, pm, rm, and sec) into an
image tree blob (ITB) file called sysfw.itb.

To establish a known-good starting point for development and testing use
U-Boot commit 7501705610 ("arm: K3: am654: Update board config for
v2018.07a enforcement in 2018.08 release of sysfw") as a baseline for the
AM654x board configuration data. Furthermore integrate SYSFW v2018.08b as
released on 09/12/2018 by way of download URL.

See included for a more complete description.
