[PATCH 02/11] drm/fbdev_generic: Use drm_driver_legacy_fb_format() for fbdev

[Frej Drejhammar]

Switch to using drm_driver_legacy_fb_format() instead of
drm_mode_legacy_fb_format() to use the same logic as for the
DRM_IOCTL_MODE_ADDFB ioctl when selecting a framebuffer format.

This is an evolved version of the changes proposed in "drm: Don't
return unsupported formats in drm_mode_legacy_fb_format" [1] following
the suggestions of Thomas Zimmermann.
