PCI: Use FIELD_GET() in Sapphire RX 5600 XT Pulse quirk
Use FIELD_GET() to remove dependences on the field position, i.e., the
shift value. No functional change intended.
Separate because this isn't as trivial as the other FIELD_GET() changes.
See 907830b0fc9e ("PCI: Add a REBAR size quirk for Sapphire RX 5600 XT
Pulse")
