Enable C7 as RP for NVMe x4

We are working on a custom board for Orin which runs C5 in endpoint and C7 to a M.2 connection for an NVME. When enabling the C7 RP in DTB (pcie@141e0000) we see the error below and the NVMe fails to be detected.

7.660780] tegra194-pcie 141e0000.pcie: Failed to find PHY entries: -22     
[    7.667696] tegra194-pcie 141e0000.pcie: Failed to parse device tree: -22    
[    7.674710] tegra194-pcie: probe of 141e0000.pcie failed with error -22      

We are flashing with ODMDATA Config 2 but with nvhs-uphy set to EP.:
****Note: there is no networking devices on this board.
Is there something we are missing in the DTB?
