similar to: [PATCH 5/7] drm/qxl: Don't set the dpms hook

These days drm core checks function pointers everywhere before calling them. So we can drop a bunch of dummy functions now.

Many DRM drivers implement an encoder with an empty implementation. This patchset adds drm_simple_encoder_init() and drm_simple_encoder_create(), which can be used by drivers instead. Except for the destroy callback, the simple encoder's implementation is empty. The patchset also converts 4 encoder instances to use the simple-encoder helpers. But there are at least 11 other drivers which can

The qxl driver uses an empty implementation for its encoder. Replace the code with the generic simple encoder.

Upcasting using a container_of macro is more typesafe, faster and easier for the compiler to optimize.

The encoder callbacks are only called in case the video mode changes. So any layout changes without mode changes will go unnoticed. Add qxl_crtc_update_monitors_config(), based on the old qxl_write_monitors_config_for_encoder() function. Hook it into the enable, disable and flush atomic crtc callbacks. Remove monitors_config updates from all other places. Fixes:

When reading the monitor config fails, don't retry forever. If it fails ten times in a row just give up to avoid the driver hangs. Also add a small delay after each attempt, so the host has a chance to complete a partial update.

Call qxl_add_monitors_config_modes() unconditionally. Do all sanity checks in that function. Fix sanity checks. monitors_config is the current monitor configuration, whereas client_monitors_config is the configuration requested by the spice client. So when filling the mode list, based on the spice client request, we need to look at client_monitors_config->count not

Try to read the client monitors config at driver load time, even without explicit notification. So in case that info was filled before the driver loaded and we've missed the notifications because of that the settings will still be used. With that place we now have to take care to properly handle a empty client monitors config, so we don't trip over an uninitialized client monitors
