firmware: arm_scpi: Add include guard to linux/scpi_protocol.h
If this header is include twice, it will generate loads of compile time error with the following below error pattern. It was reported by 0day kbuild robot on a branch pushed with double inclusion by accident. This is based on the similar change in linux/scmi_protocol.h error: conflicting types for ‘...’ note: previous declaration of ‘...’ was here error: redefinition of ‘...’ Add a header include guard just in case.
