drm/vc4: kms: Register a different drm_mode_config_funcs on BCM2711

Browse Source 
On the BCM2711, our current definition of drm_mode_config_funcs uses the
custom vc4_fb_create().

However, that function relies on the buffer allocation path that was
relying on the GPU, and is no longer relevant.

Let's create another drm_mode_config_funcs structure that we will
register on the BCM2711.
