ACPI: scan: Use acpi_bus_get_primary_device()

The acpi_get_first_physical_node() usage in acpi_create_video_bus_device()
is generally unsafe because in theory the device returned by it may be
freed at any time.

Address this issues by using acpi_bus_get_primary_device() instead of
acpi_get_first_physical_node() and dropping the device reference
acquired by it after registering the child.
