i915: Move i915_read/write out of line
With the tracing code in there they are far too big to inline.
.text savings compared to a non force inline kernel:
i915_restore_display 4393 12036 +7643
i915_save_display 4295 11459 +7164
i915_handle_error 2979 6666 +3687
i915_driver_irq_handler 2923 5086 +2163
i915_ringbuffer_info 458 1661 +1203
i915_save_vga - 1200 +1200
i915_driver_irq_uninstall 453 1624 +1171
i915_driver_irq_postinstall 913 2078 +1165
ironlake_enable_drps 719 1872 +1153
i915_restore_vga - 1142 +1142
intel_display_capture_error_state 784 2030 +1246
intel_init_emon 719 2016 +1297
and more ...
[AK: these are older numbers, with the new SNB forcewake checks
it will be even worse]
