Move Graphics Allocator HAL IPC rules to proper location Every client of Graphics Allocator HAL needs permission to (Hw)Binder IPC into the HAL. Test: Device boots, no denials to do with hal_graphics_allocator (also, removing the binder_call(hal_graphics_allocator_client, hal_graphics_allocator_server) leads to denials) Test: GUI works, YouTube works Bug: 34170079 Change-Id: I5c64d966862a125994dab903c2eda5815e336a94 2017-03-20 23:02:20 +01:00			`# HwBinder IPC from client to server`
