[Intel-gfx] [PATCH] drm/i915/uncore: fwtable read handlers are now used on all forcewake platforms

2021-09-22 Thread Matt Roper 
With the recent refactor of the uncore mmio handling, all
forcewake-based platforms (i.e., graphics version 6 and beyond) now use
the 'fwtable' read handlers.  Let's pull the assignment out of the
per-platform if/else ladder to make this more obvious.
