While there is an existing device_id:vendor_id in the driver with 64k alignment, that device_id:vendor_id is am654, which uses BAR2 instead of BAR0 as the test_reg_bar, and also has special is_am654_pci_dev() checks in the driver to disallow BAR0. In order to allow testing all BARs, add a new rk3588 entry in the driver. We intentionally do not add the vendor id to pci_ids.h, since the policy for that file is that the vendor id has to be used by multiple drivers. Hopefully, this new entry will be short-lived, as there is a series on the mailing list which intends to move the address alignment restrictions from this driver to the endpoint side. Add a new entry for rk3588 in order to allow us to test all BARs.
