drm/i915: Preallocate the debug power domain wakerefs array
Since the current size of intel_display_power_domain_set struct is
close to 1kB, it's better to use preallocated memory for it. The only
user of the intel_display_power_get/put_in_set() allocating the struct
on stack is hsw_get_pipe_config(), so we can avoid potential stack
overallocations by moving the struct here to the preallocated
intel_crtc struct (hsw_get_pipe_config() is non-reentrant wrt. each
CRTC).
