arm64: tegra: Fix Tegra194 PCIe EP compatible string 

The initialization sequence performed by the generic platform driver
pcie-designware-plat.c for a DWC based implementation doesn't work for
Tegra194. Tegra194 has a different initialization sequence requirement
which can only be satisfied by the Tegra194 specific platform driver
pcie-tegra194.c. So, remove the generic compatible string "snps,dw-pcie-ep"
from Tegra194's endpoint controller nodes.
