mei: lb: add late binding version 2

2026-04-06T09:39:55+00:00

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.
