[PATCH v2 02/10] drm/xe: Define registers used by memory based irq processing

The RING_INT_SRC_RPT_PTR register points to a cacheline in memory
to which an engine must report as source of interrupt prior to
generating an interrupt to the host.
The RING_INT_STATUS_RPT_PTR register points to the first cacheline
of the Interrupt Status Report (ISR) page (4KB) in graphics memory
to which all engines report their interrupt status.
The RING_IMR register has the interrupt enables and interrupt masks
for an engine.
We will refer to these registers shortly.
Bspec: 45963, 45964, 45965
