Hi,

this two patches are few debugfs improvements. The first adds
some helpers for reading the GT frequency, while the second patch
moves all the power management debufs functions into gt/

Thanks Chris for the reviews.

Thanks,
Andi

Changelog:
==========
v3-v4: (v3: https://lists.freedesktop.org/archives/intel-gfx/2019-December/223368.html)
 - added wakeref in frequency reading (patch 1)
 - added Chris reviewed-by in patch 1
 - sorted in alphabetical order the debugfs functions
 - removed dentry reference in the gt structure, because it's useless.

v2-v3: (v2: https://lists.freedesktop.org/archives/intel-gfx/2019-December/223277.html)
Fixed the three reviews from Chris
 - removed the 'i915' prefix from the gt pm debugfs files
 - fixed my laziness and made the debugfs pm files more gt
   oriented. Now the only dependency remaining from the
   'drm_i915_private' structure is for platform generation check.
 - restored the 'node_to_i915' to its original position, as it's
   not needed anymore.

v1-v2: (v1: https://lists.freedesktop.org/archives/intel-gfx/2019-December/222758.html)
 - renamed functions from
	intel_cagf_freq_read to intel_rps_read_actual_frequency
	intel_cagf_read to intel_rps_read_cagf
 - created an independent gt/ directory in debugfs
