boot/arm-trusted-firmware: allow using Barebox as BL33

Browse Source 
Since version 2022.04.0, Barebox now supports a generic image built
for platforms, to be used as BL33 to generate FIP images. This patch
makes it available as a choice of BL33 to be used with ATF and is
based on the similar work put into U-Boot as BL33.

This option allows to embed the Barebox generic BL33 image in
the ARM Trusted Firmware. It ensures that the Barebox package
gets built before ATF, and that the appropriate BL33
variable pointing to the generic bl33 image is passed
when building ATF.
