This avoids using the deprecated drm_get_pci_dev() and load() hook interfaces in the qxl driver. The only tricky part is to ensure TTM debugfs initialization happens after the debugfs root node is created, which is done by moving that code into the debufs_init() hook. Since the hook is called 3 times for each minor function, we make sure it is only executed for the primary minor. Tested on qemu with igt and running a WM on top of X.
