boot/opensbi: allow using U-Boot as a payload

Browse Source 
The opensbi package already allows to use Linux as a payload for
OpenSBI, but in some cases, U-Boot as payload is useful. This commit
adds a BR2_TARGET_OPENSBI_UBOOT_PAYLOAD option, modeled after the
existing BR2_TARGET_OPENSBI_LINUX_PAYLOAD.
