drm/i915: Introduce HAS_FPGA_DBG_UNCLAIMED()
Let's introduce one more of those orthogonal feature macros. This should
hopefully make the code more readable and make things easier for new platform
enabling.
This time, HAS_FPGA_DBG_UNCLAIMED() is true for platforms that have bit
31 of FPGA_DBG able to signal unclaimed writes.
