Refresh the defconfig for Renesas ARM systems:
  - Move CONFIG_DRM_PANEL_SIMPLE (moved in commit aaf7f809
    ("drm/panel: re-alphabetize the menu list")),
  - Enable warn on W+X mappings at boot (recommended, renamed in commit
    a90f0a02 ("arm: ptdump: rename CONFIG_DEBUG_WX to
    CONFIG_ARM_DEBUG_WX")).
