drm/radeon: Log Subsystem Vendor and Device Information

commit d522d9cc5bdd41214084383fc3e6d882f6916a78 upstream.

    Log PCI subsystem vendor and subsystem device ID in addition to
    PCI vendor and device ID during kernel mode initialisation. This helps
    to better identify radeon devices of third-party vendors, e. g. for
    bug analysis.

    Tested for kernel 2.6.35, 2.6.38 and 3.0 on Asus M2A-VM HDMI board
