soc/amd/stoneyridge/Kconfig: use correct VGA_BIOS_ID

Fix the VGA_BIOS_ID IDs to match the PCI IDs in the VBIOS binaries and
the PCI ID Stoneyidge's map_oprom_vendev returns. This fixes the problem
that the display wasn't initialized due to not finding the VBIOS file in
CBFS. This bug in the Stoneyridge Kconfig was unmasked by commit
42f0396a1028 ("device/pci_rom: rework PCI ID remapping in
pci_rom_probe").

TEST=Display in Careena lights up again.
