soc: aspeed: mctp: Add IOCTL to set own EID
The driver doesn't implement MCTP logic, which means that it requires
its clients to prepare valid MCTP over PCIe packets.
Because we support MCTP stacks in both kernel and userspace, and since
MCTP protocol is a part of userspace, we need userspace to update own
EID information in kernel to provide it for in-kernel aspeed-mctp
clients.
Previously, own EID information was updated by userspace using
SET_EID_INFO which now is deprecated and replaced by SET_EID_EXT_INFO to
pass CPU EID and Domain ID mappings.
To provide own EID information for in-kernel clients, add a dedicated
IOCTL.
