mei: lb: add late binding version 2

Browse source

The second Late Binding version allows to send payload bigger
than client MTU by splitting it to chunks and uses separate
firmware client for transfer.

The component interface is unchanged and driver doing all splitting.

Only one Late Binding version is supported by firmware.
When Late binding version 2 is supported, the new client is advertised
by firmware and existing MKHI will have version 2.
This helps driver to select the right mode of work.
