[PATCH 3/4] ARM: k3: am62l: Add dedicated config option for OP-TEE

[Sascha Hauer <s.hauer@pengutronix.de>]

Until now we compiled in the OP-TEE binary into the AM62l images when it
exists. The when-it-exists part makes it hard to add a dependeny on the
file, so add a dedicated config option for it.
