2021-10-18	optee: add FF-A support	Jens Wiklander
	Adds support for using FF-A [1] as transport to the OP-TEE driver. Introduces struct optee_msg_param_fmem which carries all information needed when OP-TEE is calling FFA_MEM_RETRIEVE_REQ to get the shared memory reference mapped by the hypervisor in S-EL2. Register usage is also updated to include the information needed. The FF-A part of this driver is enabled if CONFIG_ARM_FFA_TRANSPORT is enabled.
