[RFC 10/21] drm/qxl: Remove FB_KMS_HELPER and FB related config options

Remove FB_* config options since the driver doesn't call any fbdev
functions directly.
Remove FB_KMS_HELPER as this would now be selected by the top level
FBDEV_EMULATION config option. If the fbdev emulation isn't selected,
the drm_fb_helper functions will be stubbed out.
The code relying on DEFERRED_IO can't be stubbed out using drm_fb_helper
functions. This is because the deferred io members in fbdev core structs
are defined based on whether FB_DEFERRED_IO is defined or not.
For now, wrap around deferred io code with an #ifdef check for
CONFIG_DEFERRED_IO. We could consider creating stub fb helper functions
here, but this would require some changes in the core fbdev structs.
