patches: Add patch for CONFIG_DRM_OFDRM=m and CONFIG_FB_OF=y

OpenSUSE has set 'CONFIG_DRM_OFDRM=m', which causes the link errors
noted in the commit message of this patch. I have pinged the patch
upstream so that it will hopefully make it to Linus sooner rather than
later.

+Subject: [PATCH] fbdev: make offb driver tristate
+From: Randy Dunlap <rdunlap@infradead.org>
+Date: Fri, 25 Nov 2022 16:04:01 -0800
+Message-Id: <20221126000401.25302-1-rdunlap@infradead.org>
+MIME-Version: 1.0
+Content-Type: text/plain; charset="utf-8"
+Content-Transfer-Encoding: 8bit
+
+Make the offb (Open Firmware frame buffer) driver tristate,
+i.e., so that it can be built as a loadable module.
+
+However, it still depends on the setting of DRM_OFDRM
+so that both of these drivers cannot be builtin at the same time
+nor can one be builtin and the other one a loadable module.
+
+Build-tested successfully with all combination of DRM_OFDRM and FB_OF.
+
+This fixes a build issue that Michal reported when FB_OF=y and
+DRM_OFDRM=m:
+
