drm/i915: Add pretty printer for modparams
We dump modparams in few places (debugfs, gpu_error) using different
functions. Lets add reusable function to avoid code duplication.
add/remove: 1/0 grow/shrink: 0/2 up/down: 1096/-2339 (-1243)
Function old new delta
i915_params_dump - 1096 +1096
i915_capabilities 1353 185 -1168
i915_error_state_to_str 5507 4336 -1171
Total: Before=1285716, After=1284473, chg -0.10%
v2: use forward decl rather than include (Chris)
