ipq40xx: enlarge PCIe BAR size
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".
