drm/tegra: Remove existing framebuffer only if we support display

Browse source

[ Upstream commit 86bf8cfda6 ]

Tegra DRM doesn't support display on Tegra234 and later, so make sure
not to remove any existing framebuffers in that case.

v2: - add comments explaining how this situation can come about
    - clear DRIVER_MODESET and DRIVER_ATOMIC feature bits
