soc/amd/picasso: Use common block graphics driver

This change selects common block graphics driver for Picasso and also
adds PCI ID for Family 17h graphics controller to the graphics
driver.

Since the common driver provides .acpi_name() callback for graphics
device, soc_acpi_name() no longer needs to provide the ACPI name for
graphics device.
