FROMLIST: firmware: arm_scmi: port Reset protocol to new protocols interface

Browse Source 
Convert internals of protocol implementation to use protocol handles and
expose a new protocol operations interface for SCMI driver using the new
get/put common operations, while keeping the old handle->reset_ops still
around to ease transition.

Remove handle->reset_priv now unused.
