Three RPC functions are added to support RPMB probing and properly align
RPMB frames, OPTEE_RPC_CMD_RPMB_PROBE_RESET,
OPTEE_RPC_CMD_RPMB_PROBE_NEXT, and OPTEE_RPC_CMD_RPMB_FRAMES.
OPTEE_RPC_CMD_RPMB_PROBE_RESET resets probing to a well known state and
returns the shared memory type needed when allocating shared memory for
communication with later RPMB functions.
OPTEE_RPC_CMD_RPMB_PROBE_NEXT selects the next RPMB device and returns
its device information. Later calls to OPTEE_RPC_CMD_RPMB will use this
selected device.
OPTEE_RPC_CMD_RPMB_FRAMES sends the raw RPMB frames to normal world for
further routing to the RPMB device.
tee_rpmb_reinit() is added to allow re-initializing the RPMB FS if a
boot stage has used RPMB.
Backwards compatibility is maintained by falling back to the old type of
initialization if OPTEE_RPC_CMD_RPMB_PROBE_RESET returns
TEE_ERROR_NOT_SUPPORTED.
Whether RPMB devices are probed by the kernel or tee-supplicant is
decided by the kernel driver where the shared memory type returned by
OPTEE_RPC_CMD_RPMB_PROBE_RESET plays a vital role.
