drm/i915/gen9: Use flush_work to synchronize with dmc loader

During driver unload to ensure we dont have any pending task,
flush_work added to complete firmware loading task.

v1: Initial version.

v2: As per review comments from Daniel,
Removed flush_work from skl_set_power_well. As we have taken
power well refernece and rpm count during firmware loading
by using display_power_domain_get/put - this will always
ensure rpm will be blocked if firmware is not loaded.
