drm/i915: deduplicate frequency dump on debugfs Although commit 9dd4b065446a ("drm/i915/gt: Move pm debug files into a gt aware debugfs") says it was moving debug files to gt/, the i915_frequency_info file was left behind and its implementation copied into drivers/gpu/drm/i915/gt/debugfs_gt_pm.c. Over time we had several patches having to change both places to keep them in sync (and some patches failing to do so). The initial idea was to remove i915_frequency_info, but there are user space tools using it. From a quick code search there are other scripts and test tools besides igt, so it's not simply updating igt to get rid of the older file. Here we export a function using drm_printer as parameter and make both show() implementations to call this same function. Aside from a few variable name differences, for i915_frequency_info this brings a few lines that were not previously printed: RP UP EI, RP UP THRESHOLD, RP DOWN THRESHOLD and RP DOWN EI. These came in as part of commit 9c878557b1eb ("drm/i915/gt: Use the RPM config register to determine clk frequencies"), which didn't change both places.

drm/i915: rename debugfs_gt_pm files We shouldn't be using debugfs_ namespace for this functionality. Rename debugfs_gt_pm.[ch] to intel_gt_pm_debugfs.[ch] and then make functions, defines and structs follow suit.
