Subject: [PATCH 2/4] platform/chrome: cros_ec_typec: Use dev_err_probe() more

There's some debug prints here that can be upgraded to dev_err_probe()
so that we don't have to fish out the error messages when a true error
happens. If they're simply probe defers then the kernel will keep silent
but if they're true errors we'll see the errors in the logs.
