The Google Tensor SoC USB PHY is only present on Google Tensor G5
(Laguna) SoCs. Hence add a dependency on ARCH_GOOGLE, to prevent asking
the user about this driver when configuring a kernel without Google
Tensor SoC support.

ARCH_GOOGLE is not yet upstream, but that doesn't hurt.I can see your point, and have no objection, but for context, Greg had asked to not add dependencies on a config option that might or might not get added in the future - ARCH_GOOGLE: https://lore.kernel.org/all/2025121728-reliably-crabgrass-2601@gregkh/ (local) Maybe an alternative would be to make it default=n, and change that default once ARCH_GOOGLE gets added?
