Subject: [PATCH] powerpc/configs: Add debug config fragment

From: Andrew Donnellan <[email-masked]>
Date: Thu, 1 Aug 2019 14:58:55 +1000

Add a debug config fragment that we can use to put useful debug options
into.

Currently we only define a target for powernv[_be]_debug_defconfig, and the
only option included is to enable debugfs SCOM access.
