drm/i915/display: use a macro to initialize subplatforms

Make it easier to change the underlying structures by using a macro
similar to PLATFORM() for initialization.

The subplatform names in debug logs change slightly as they now reflect
the enum rather than manually entered names. For example, RAPTORLAKE_S
rather than RPL-S.
