Subject: drm/kmb: Enable support for framebuffer console
Git-commit: 099afadc533febb0ad789ee61eef41a3d5d8bab2
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Enable support for fbcon (framebuffer console).

v2: added missing static clk_enable
v3: removed module parameter, use fbdev_emulation instead. Use
preferred depth of 24 for color depth. (Thomas Z.)
