drm/i915: add forcewake functions that don't touch runtime PM
To solve a chicken-and-egg problem. Currently when we get/put forcewake we also get/put runtime PM and this works fine because the runtime PM code doesn't need forcewake. But we're going to merge PC8 and runtime PM into a single feature, and the PC8 code (the LCPLL code) does need the forcewake, so that specific piece of code needs to call the _no_rpm version so it doesn't try to get runtime PM in the code that gets runtime PM. For now the new functions are unused, we'll use them on the patch that merges PC8 with runtime PM. Also notice that, so simplify things, the put() function doesn't use the workqueue, since the workqueue also puts runtime PM. Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com>
