ipq40xx: enlarge PCIe BAR size

Browse Source 
David Bauer reported that the VDSL modem (attached via PCIe)
on his AVM Fritz!Box 7530 was complaining about not having
enough space in the BAR. A closer inspection of the old
qcom-ipq40xx.dtsi pulled from the GL-iNet repository listed:

| qcom,pcie@80000 {
|       compatible = "qcom,msm_pcie";
|       reg = <0x80000 0x2000>,
|             <0x99000 0x800>,
|             <0x40000000 0xf1d>,
|             <0x40000f20 0xa8>,
|             <0x40100000 0x1000>,
|             <0x40200000 0x100000>,
|             <0x40300000 0xd00000>;
|       reg-names = "parf", "phy", "dm_core", "elbi",
|                       "conf", "io", "bars";

Matching the reg-names with the listed reg leads to
<0xd00000> as the size for the "bars".
