firmware: scmi: support to manage SCMI protocol drivers with a linker-genetated array
U_BOOT_SCMI_PROTO_DRIVER macro is used to add a SCMI protocol driver to scmi_proto_driver list. scmi_proto_driver_get() function can be used to match a SCMI protocol id and its driver. Signed-off-by: Alice Guo <alice.guo@nxp.com>
