[Intel-gfx] [PATCH] drm/i915: move i915_fence_{context_, }timeout() to i915_sw_fence.[ch]

[Jani Nikula]

Maybe there was a grand plan with i915_fence_timeout() and
i915_fence_context_timeout() and i915_config.c, but that seems to have
been lost a bit.

Just move the functions to i915_sw_fence.[ch] from i915_drv.h and
i915_config.c, and remove the latter.
