drm/i915/dram: Don't call skl_get_dram_info()/skl_get_dram_type() on icl

Currently the icl codepaths first determine the memory type from the
memory controller registers (via skl_get_dram_info()->skl_get_dram_type())
and then overwrite the results with icl_pcode_read_mem_global_info().
Get rid of the pointless (and potentially incorrect) skl_get_dram_type()
stuff.
