Cadence IP in J721E supports a maximum of 32 outbound regions. However
commit 4e5833884f66 ("arm64: dts: ti: k3-j721e-main: Add PCIe device
tree nodes") incorrectly added this as 16 outbound regions. Now that
"cdns,max-outbound-regions" is an optional property with default value
as 32, remove "cdns,max-outbound-regions" from endpoint DT node.
Fixes: 4e5833884f66 ("arm64: dts: ti: k3-j721e-main: Add PCIe device tree nodes")

Remove "syscon" nodes added for pcieX_ctrl and have the PCIe node
point to the parent with an offset argument. This change is as discussed in [1]
