[Intel-gfx] [PATCH 2/3] drm/i915/perf: move pollin setup to non hw specific code

[Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>]

From: Lionel Landwerlin <lionel.g.landwerlin@intel.com>

This isn't really gen specific stuff, so just move it to the common
code.

v2: Rebase (Umesh)
v3: Remove comment, pollin is a per stream state already (Ashutosh)
