Subject: [PATCH 5.15 373/913] ARM: configs: multi_v5_defconfig: re-enable DRM_PANEL and FB_xxx

From: Andre Przywara <andre.przywara@....com>

[ Upstream commit 9c44d0805f949c56121b4ae6949fb064537bf198 ]

Commit 91185d55b32e ("drm: Remove DRM_KMS_FB_HELPER Kconfig option")
led to de-selection of CONFIG_FB, which was a prerequisite for
BACKLIGHT_CLASS_DEVICE, which CONFIG_DRM_PANEL_SIMPLE depended on.
Explicitly set CONFIG_FB, to bring DRM_PANEL_SIMPLE, DRM_PANEL_EDP,
FB_IMX and FB_ATMEL back into the generated .config.
This also adds some new FB related features like fonts and the
framebuffer console.

See also commit 8c1768967e27 ("ARM: config: mutli v7: Reenable FB
dependency"), which solved the same problem for multi_v7_defconfig.

This relies on [1], to fix a broken Kconfig dependency.
