Subject: [PATCH 4/4] drm/gma500: avoid Woverride-init warning

From: Arnd Bergmann <arnd@...db.de>

gcc -Wextra notices that one of the fields in psbfb_roll_ops has two
initializers:

drivers/gpu/drm/gma500/framebuffer.c:185:20: warning: initialized field overwritten [-Woverride-init]

Open-code this instead, leaving out the extraneous initializers for
.fb_pan_display.

Fixes: 3da6c2f3b730 ("drm/gma500: use DRM_FB_HELPER_DEFAULT_OPS for fb_ops")
