PCI: rockchip: Write PCI Device ID to correct register

Browse source

commit 1f1c42ece1 upstream.

Write PCI Device ID (DID) to the correct register. The Device ID was not
updated through the correct register. Device ID was written to a read-only
register and therefore did not work. The Device ID is now set through the
correct register. This is documented in the RK3399 TRM section 17.6.6.1.1
