zephyr: look for board-specific configuration
To build Zephyr as a bootloader will typically require
overriding the default flash regions where the binary lives,
and possibly other board-specific configuration directives.
Look for boot/zephyr/targets/$(BOARD).conf and include it
in the kernel configuration if it exists.
