[PATCH v2 6/6] PCI: dw-rockchip: Describe resizable BARs as resizable BARs

[Niklas Cassel]

Looking at "11.4.4.29 USP_PCIE_RESBAR Registers Summary" in the rk3588 TRM,
we can see that none of the BARs are Fixed BARs, but actually Resizable
BARs.

I couldn't find any reference in the rk3568 TRM, but looking at the
downstream PCIe endpoint driver, rk3568 and rk3588 are treated as the same,
so the BARs on rk3568 must also be Resizable BARs.

Now when we actually have support for Resizable BARs, let's configure
these BARs as such.
