[PATCH 2/6] drm/i915/gvt: use proper i915_reg_t for calc_index() parameters

[Jani Nikula <jani.nikula@xxxxxxxxx>]

In order to be able to use the proper register macros instead of the
underscore prefixed ones, pass i915_reg_t for the calc_index()
parameters.

Side note: DSPSURF is really about planes, not pipes. Fixed stride
doesn't work for plane C for CHV (but that's okay for gvt). This doesn't
support planes beyond C either. But all that is unrelated to the change
at hand.
