drm/i915/dram: Consolidate logging of DRAM type

drm/i915/dram: Consolidate logging of DRAM type

Instead of logging the dram type in the per version/platform function,
do it in the generic one. This fixes a few discrepancies depending on
the platform:

	- There was no DRAM type logging for graphics version 12 and
	  above
	- For graphics version 11, it would log the DRAM type in
	  skl_get_dram_info(), but could possibly override it later
	  without any log in icl_pcode_read_mem_global_info()

For bxt_get_dram_info(), there's no need to log the type for each dimm,
as the drm_WARN_ON() already covers the case they are not all the same.

This maintains the behavior of skl_get_dram_info() that would log the
DRAM type even on failures.
