[Intel-gfx] [PATCH 0/2] Introduce multitile support

Hi,

This is the second series that prepares i915 to host multitile
platforms. It introduces the for_each_gt() macro that loops over
the tiles to perform per gt actions.

This patch is a combination of two patches developed originally
by Abdiel, who introduced some refactoring during probe, and then
Tvrtko has added the necessary tools to start using the various
tiles.

The second patch re-organises the sysfs interface to expose the
API for each of the GTs. I decided to prioritise this patch
over others to unblock Sujaritha for further development.

A third series will still follow this.
