firmware: scmi: Conditionally compile protocol support

Browse Source 
Add conditional compilation for SCMI protocol support in scmi_get_protocol()
and scmi_add_protocol() based on corresponding Kconfig options. This ensures
that only the enabled protocols are compiled and accessed, and reducing binary
size.
