From: Andi Shyti <andi.shyti@xxxxxxxxx>
When registering debugfs files the intel gt debugfs library
forces a 'struct *gt' private data on the caller.
There might be different needs, therefore make it generic by
adding one more argument to the "debugfs_register_files()"
function which gets the generic void private data as argument.
Still keep it simple by defining a wrapper where struct *gt is
the chosen private data to be stored.
I take the chance to rename the functions by using "intel_gt_" as
prefix instead of "debugfs_".

Changelog:
v2:
- the eval function is made generic as suggested by Daniele.
