conf, recipes-bsp: support building for K3 R5F cores via multiconfig

K3 Multicore SoC architecture defines different functional domains, each
containing specific processing cores and peripherals. Early boot is normally
handled by running bootloader and loading SYSFW on MCU Cortex-R5F core:
https://git.ti.com/cgit/ti-u-boot/ti-u-boot/tree/board/ti/am65x/README
https://git.ti.com/cgit/ti-u-boot/ti-u-boot/tree/board/ti/j721e/README

This change adds support for building bootloader and SYSFW ITB image for
K3 Cortex-R5F cores via multiconfig.
