From: Mario Limonciello <mario.limonciello at amd.com>

Shortly after the series for introducing boot_display was merged
Manivannan Sadhasivam suggested that it's better not to introduce
new top level PCI attributes where possible.

He proposed that the boot_display attribute should be provided by DRM
instead and that userspace should look for that.

Change the owner of `boot_display` from the PCI device to the DRM card.
This should also have the side effect that non-PCI DRM drivers can
add support more easily.

NOTE: If acceptable this should be merged through the PCI tree as it
depends upon changes and symbols from the boot_display series.
