Hi Alejandro,
Please feel free to pull in the patches in this series into your type2 series.
Although I may just pull these into the 6.12 merge window to make things easier
for you.

The patches pulls out the related mailbox bits and form a 'struct cxl_mailbox'. In
v2 Jonathan suggested that we keep cxl_mbox embedded. So I moved it back to be
embedded. For the type2 devices that does not use mailbox, it can just not have
the mailbox struct at all.

v3
- moved the other cxl headers into the linux/cxl directory.
- Moved rcuwait.h header into mailbox.h (Alison)
