[PATCH 1/2] drm/i915/dram: Add missing INTEL_DRAM str conversions

[Lucas De Marchi]

Some new dram types were added without adding the corresponding string
conversion, probably because it's not being used by recent platforms.
Add them, together with a BUILD_BUG_ON() to ensure it keeps in sync, in
preparation to make use of them in recent platforms.
