Fixed in powerpc (some future/next branch) by:

commit 665d8d58761cba41147fe7e98e2ceed1cbf603a2
Author: Michael Ellerman <mpe@xxxxxxxxxxxxxx>
Date: Mon Feb 1 12:25:03 2021 +1100

powerpc/akebono: Fix unmet dependency errors

The AKEBONO config has various selects under it, including some with
user-selectable dependencies, which means those dependencies can be
disabled. This leads to warnings from Kconfig.
