drm/i915/xehp: Determine which tile raised an interrupt

The first step of interrupt handling is to read a tile0 register that
tells us in which tile the interrupt happened; we can then we read the
usual interrupt registers from the appropriate tile.

Note that this is just the first step of handling interrupts properly on
multi-tile platforms.  Subsequent patches will convert other parts of
the interrupt handling flow.
