video_core/GPU Implemented the GPU PFIFO puller semaphore operations. (#1908)
* Implemented the puller semaphore operations. * Nit: Fix 2 style issues * Nit: Add Break to default case. * Fix style. * Update for comments. Added ReferenceCount method * Forgot to remove GpuSmaphoreAddress union. * Fix the clang-format issues. * More clang formatting. * two more white spaces for the Clang formatting. * Move puller members into the regs union * Updated to use Memory::WriteBlock instead of Memory::Write* * Fix clang style issues * White space clang error * Removing unused funcitons and other pr comment * Removing unused funcitons and other pr comment * More union magic for setting regs value. * union magic refcnt as well * Remove local var * Set up the regs and regs_assert_positions up properly * Fix clang error
