Add a linker section to xtensa where KUnit can put references to its
test suites. This patch is an early step in transitioning to dispatching
all KUnit tests from a centralized executor rather than having each as
its own separate late_initcall.

If you ever find yourself modifying multiple arch linker scripts for a
series, something has gone wrong. ;)
