[Buildroot] [PATCH 22/23] uboot: apply xtensa overlay

[Max Filippov <jcmvbkbc@gmail.com>]

Xtensa core configuration must be added to U-Boot before it can be
built for that xtensa CPU variant. Extract configuration files from the
xtensa overlay as is done for other packages that need to be configured
for a specific xtensa core.
