Drop the vivid dependency on CONFIG_FB by compiling out parts of the
code that make use of the framebuffer API when not enabled. This is
particularly useful as CONFIG_FB is not selected any more by
DRM_FBDEV_EMULATION.

Notes:
Changes in v2:
* fix Makefile conditional for when CONFIG_FB=m
* compile-out bit 16 (framebuffer) when no CONFIG_FB

vivid-osd depends on FB_CFB_FILLRECT, FB_CFB_COPYAREA, and FB_CFB_IMAGEBLIT,
which are not selected anymore, and linking fails if CONFIG_FB is enabled, but
the others are disabled.

I just sent a v3 which introduces a separate config to select
those dependencies when enabling framebuffer support in vivid.
In principle this should fix the linkage issue while still
dropping the hard dependency on CONFIG_FB. I've tried various
combinations of built-in and module options for CONFIG_FB and
CONFIG_VIDEO_VIVID and they all built fine, although that's not
really comprehensive build testing so I'll keep an eye open for
test bot results.
Thanks,
Guillaume
