Enable the existing make variable KEY that was introduced to specify
the signing key used to sign SYSFW for use on HS devices to also be
used to sign SYSFW images destined for GP devices, overriding the
default random key that is used for signing.

For that we can use macros that rely on BIT(x) in the different
configuration files we need to actually have that underlying macro
defined in the first place so go ahead and add the missing
definition.

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 README.md for a more complete description.
