drm/i915/gsc: add gsc as a mei auxiliary device

GSC is a graphics system controller, it provides
a chassis controller for graphics discrete cards.

There are two MEI interfaces in GSC: HECI1 and HECI2.

Both interfaces are on the BAR0 at offsets 0x00258000 and 0x00259000.
GSC is a GT Engine (class 4: instance 6). HECI1 interrupt is signaled
via bit 15 and HECI2 via bit 14 in the interrupt register.

This patch exports GSC as auxiliary device for mei driver to bind to
for HECI2 interface and prepares for HECI1 interface as
it will follow up soon.
