similar to: [PATCH v4] drm/virtio: Add option to disable KMS support

From: Rob Clark <robdclark at chromium.org> Add a build option to disable modesetting support. This is useful in cases where the guest only needs to use the GPU in a headless mode, or (such as in the CrOS usage) window surfaces are proxied to a host compositor. As the modesetting ioctls are a big surface area for potential security bugs to be found (it's happened in the past, we

Non-KMS drivers store state in struct drm_driver. This bloats the structure for KMS drivers and prevents it from being declared with 'static const' qualifiers. Moving the non-KMS state into a separate data structure resolves this.

All non-kms driver fields are now located in struct drm_legacy_state. A driver-wide instance is available via struct drm_driver.legacy. The call sites test if the driver is marked with DRIVER_LEGACY before accessing the fields.
