platform/chrome: cros_ec_typec: Check ec platform device pointer
It is possible that parent device for cros_ec_typec device is already
available, but ec pointer in parent driver data isn't populated yet. It
may happen when cros_typec_probe is running in parallel with
cros_ec_register. This leads to NULL pointer dereference when
cros_typec_probe tries to get driver data from typec->ec->ec->dev.
Check if typec->ec->ec is set before using it in cros_typec_probe.
