Merge branch 'ipa-next'

Alex Elder says:

====================
net: ipa: a few more small items

This series consists of three small sets of changes.  Version 2 adds
a patch that avoids a warning that occurs when handling a modem
crash (I unfortunately didn't notice it earlier).  All other patches
are the same--just rebased.

The first three patches allow a few endpoint features to be
specified.  At this time, currently-defined endpoints retain the
same configuration, but when the monitor functionality is added in
the next cycle these options will be required.

The fourth patch simply removes an unused function, explaining also
why it would likely never be used.

The fifth patch is new.  It counts the number of modem TX endpoints
and uses it to determine how many TREs a transaction needs when
when handling a modem crash.  It is needed to avoid exceeding the
limited number of commands imposed by the last four patches.

And the last four patches refactor code related to IPA immediate
commands, eliminating an unused field and then simplifying and
removing some unneeded code.
