[PATCH v2025.09.y 41/49] ARM: k3: am62l: Add dedicated config option for OP-TEE

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: 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.
