The log struct is the only thing the function needs (apart from
the seq_file), so we can pass just that instead of the whole dev_priv.

v2: Split this change to its own patch (Michal)

maybe to avoid polluting i915_debugfs.c we should move this function to
gt/uc/intel_guc_log.c as universal printer:

On that note, I'm going to split display bits from i915_debugfs.c to a
file of its own under display/ [1]. I think there's enough guc/huc stuff
to warrant moving them to a separate file maybe under gt/uc/.

Andi is already looking at moving all the GT bits under gt/, so the uc functions will move as part of that.

too many dots ... this is "guc" info function, maybe we should have:

        struct intel_guc *guc = &dev_priv->gt.uc.guc;
or
        struct intel_gt *gt = &dev_priv->gt;
        struct intel_uc *uc = &gt->uc;
        struct intel_guc *guc = &uc->guc;

as that "guc" is likely to be reused in "more" below
