Hence add a dependency on ARCH_QCOM, to prevent asking the user about this driver when configuring a kernel without Qualcomm platform support.

QTEE clients can invoke an instance of qcomtee_object to access QTEE services. If this invocation produces a new object in QTEE, an instance of qcomtee_object will be returned. Similarly, QTEE can request services from by issuing a callback request, which invokes an instance of qcomtee_object. Implement initial support for exporting qcomtee_object to userspace and QTEE, enabling the invocation of objects hosted in QTEE and userspace through the TEE subsystem.
