drm/xe/hwmon: Treat hwmon as a per-device concept

Browse source

There's only one instance of hwmon per device, and MMIO access to it is
always done through the root tile.  The code has been passing around a
pointer to the root tile's primary GT, which is confusing since this
isn't really a GT-level concept.  Replace that pointer with an xe_device
pointer and use xe_root_mmio_gt(xe) to get a pointer when we need to do
register MMIO.  This makes things easier to follow, and also cleans up
the code in preparation for a much larger MMIO register access overhaul
that's coming soon.
