firmware: arm_scmi: Add include guard to linux/scmi_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.
error: conflicting types for ‘...’
note: previous declaration of ‘...’ was here
error: redefinition of ‘...’
Add a header include guard just in case.
