drm/i915: Hold irq uncore.lock when initialising fw_domains
Acquiring the forcewake domain asserts that it is in an atomic section
(as we always expect to be under the uncore.lock). This is true except for
initialising the domains on Ivybridge, and so we generate a warning.
Wrap the manual usage of fw_domains inside the spin_lock.
