[PATCH v22 net-next 03/12] net/nebula-matrix: add channel wire opcode enum definitions

[illusion.wang]

From: illusion wang <illusion.wang@xxxxxxxxxxxxxxxxx>

Add enum nbl_chan_msg_type into nbl_def_channel.h, defining all
PF/VF/firmware channel wire opcodes used for inter-component mailbox
communication.

Each enumerator carries an explicit fixed numeric value, acting as stable
wire-format message ID shared between driver and firmware.

ABI constraint: New opcodes must only be appended before
NBL_CHAN_MSG_MAILBOX_MAX.
Reordering, inserting or deleting existing entries will break
cross-version driver-firmware interoperability. Any modification to
existing opcode assignments requires coordinated firmware ABI change.

This commit introduces the opcode ID enumeration. Message payload
structures and complete channel layer logic will be added in subsequent
separate patches.
