drm/i915/dram: bypass fsb/mem freq detection on dg2 and no display
Non-display now calls the intel_fsb_freq() and intel_mem_freq()
functions, so we don't have to have the frequencies initialized for dg2
or non-display cases.
This is in preparation for unifying the pre-gen9 handling in dram info.
DG2 remains a special case as described in commit 5eb6bf0b44e7
("drm/i915/dg2: Don't read DRAM info").
v2: Rebase
