[PATCH 06/13] drm/vc4: Split variable instantiation of vc4_debugfs_regset32()

[Maíra Canal <mcanal@xxxxxxxxxx>]

Considering that there are multiple ways to instantiate a
drm_debugfs_entry, as kms object's debugfs entries were introduced,
split vc4_debugfs_regset32() into two functions: one to deal with the
drm_printer and the other to instantiate the proper variables.
