arm64: defconfig: Enable QCOMTEE module for QTEE-enabled Qualcomm SoCs

All Qualcomm SoCs starting from SM8650 provide access to the Qualcomm
Trusted Execution Environment (QTEE) through the SMCInvoke interface,
implemented by the QCOMTEE driver. QTEE runs in the Secure World domain
on ARM64 CPUs and exposes secure services to Linux running in the Normal
World domain.

This change enables the QCOMTEE driver as a module to support
communication with QTEE.

QCOMTEE has been tested on a Qualcomm RB3Gen2 board by loading and
executing a Trusted Application via tests hosted at
github.com/qualcomm/minkipc.
