Subject: drm/ast: Remove reference to struct drm_device.pdev

From: Thomas Zimmermann <tzimmermann@suse.de>

commit 0ecb51824e838372e01330752503ddf9c0430ef7 upstream.

Using struct drm_device.pdev is deprecated. Upcast with to_pci_dev()
from struct drm_device.dev to get the PCI device structure.

v9:
	* fix remaining pdev references
