[PATCH] drm/hyperv-drm: Include framebuffer and EDID headers

[Thomas Zimmermann <tzimmermann@xxxxxxx>]

Fix a number of compile errors by including the correct header
files. Examples are shown below.

  ../drivers/gpu/drm/hyperv/hyperv_drm_modeset.c: In function 'hyperv_blit_to_vram_rect':
  ../drivers/gpu/drm/hyperv/hyperv_drm_modeset.c:25:48: error: invalid use of undefined type 'struct drm_framebuffer'
   25 |         struct hyperv_drm_device *hv = to_hv(fb->dev);
      |                                                ^~

  ../drivers/gpu/drm/hyperv/hyperv_drm_modeset.c: In function 'hyperv_connector_get_modes':
  ../drivers/gpu/drm/hyperv/hyperv_drm_modeset.c:59:17: error: implicit declaration of function 'drm_add_modes_noedid' [-Werror=implicit-function-declaration]
   59 |         count = drm_add_modes_noedid(connector,
      |                 ^~~~~~~~~~~~~~~~~~~~

  ../drivers/gpu/drm/hyperv/hyperv_drm_modeset.c:62:9: error: implicit declaration of function 'drm_set_preferred_mode'; did you mean 'drm_mm_reserve_node'? [-Werror=implicit-function-declaration]
   62 |         drm_set_preferred_mode(connector, hv->preferred_width,
      |         ^~~~~~~~~~~~~~~~~~~~~~
