Subject: [PATCH v4 06/11] arch: xtensa: add linker section for KUnit test suites

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.
