[PATCH] drm/i915: Use designated initializers for init/exit table

[Kees Cook]

The kernel builds with -Werror=designated-init, and __designated_init
is used by CONFIG_GCC_PLUGIN_RANDSTRUCT for automatically selected (all
function pointer) structures. Include the field names in the init/exit
table. Avoids warnings like:

drivers/gpu/drm/i915/i915_module.c:59:4: error: positional initialization of field in 'struct' declared with 'designated_init' attribute [-Werror=designated-init]
