firmware: arm_scmi: Constify struct scmi_voltage_proto_ops
Constify struct scmi_voltage_proto_ops since the driver never modifies
it. Placing it in read-only memory (.rodata) improves hardening,
particularly because it contains function pointers.
x86_64 (allmodconfig) size impact:
Before:
text data bss dec hex filename

After:
