    optee: isolate smc abi

    Isolate the ABI based on raw SMCs. Code specific to the raw SMC ABI is
    moved into smc_abi.c. This makes room for other ABIs with a clear
    separation.

    The driver changes to use module_init()/module_exit() instead of
    module_platform_driver(). The platform_driver_register() and
    platform_driver_unregister() functions called directly to keep the same
    behavior. This is needed because module_platform_driver() is based on
    module_driver() which can only be used once in a module.

    A function optee_rpc_cmd() is factored out from the function
    handle_rpc_func_cmd() to handle the ABI independent part of RPC
    processing.

    This patch is not supposed to change the driver behavior, it's only a
    matter of reorganizing the code.
