Subject: [PATCH next] phy: google: fix build dependency for Google Tensor USB PHY

The Google Tensor USB PHY driver uses the Type-C switch framework to
handle orientation changes. However, the Kconfig did not specify a
dependency on the TYPEC framework, leading to undefined reference
errors when building for architectures or configurations where
CONFIG_TYPEC is disabled or configured as a module.

Add 'depends on TYPEC' to the PHY_GOOGLE_USB entry to ensure all
required symbols are available during linking.

Fixes: cbce66669c82 ("phy: Add Google Tensor SoC USB PHY driver")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202601210825.ELrpQeED-lkp@intel.com/
