PCI: dw-rockchip: Describe Resizable BARs as Resizable BARs
Looking at section "11.4.4.29 USP_PCIE_RESBAR Registers Summary" in the Technical Reference Manual (TRM) for RK3588, we can see that none of the BARs are Fixed BARs, but actually Resizable BARs. I couldn't find any reference in the TRM for RK3568, but looking at the downstream PCIe endpoint driver, both 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.
