Subject: [PATCH V4] PCI: dwc: tegra194: Broaden architecture dependency

Replace ARCH_TEGRA_194_SOC dependency with a more generic ARCH_TEGRA
check for the Tegra194 PCIe controller, allowing it to be built on
Tegra platforms beyond Tegra194. Additionally, ensure compatibility
by requiring ARM64 or COMPILE_TEST.
