Rockchip rk3588 requires 64k alignment.
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.
