cxl: Move mailbox related bits to the same context
Create a new 'struct cxl_mailbox' and move all mailbox related bits to
it. This allows isolation of all CXL mailbox data in order to export
some of the calls to external kernel callers and avoid exporting of CXL
driver specific bits such has device states. The allocation of
'struct cxl_mailbox' is also split out with cxl_mailbox_init() so the
mailbox can be created independently.
