ARM: configs: Update Integrator defconfig

This updates the Integrator defconfig for the changes
in the v5.14-rc1 kernel:

- The Framebuffer CONFIG_FB needs to be explicitly selected
  or we don't get any framebuffer anymore. DRM has stopped to
  select FB because of circular dependency.
- Drop the unused Matrox FB drivers that are only used with
  specific PCI cards.

Fixes: f611b1e7 ("drm: Avoid circular dependencies for CONFIG_FB")
