Establish the rule that header files are always included in sorted
(POSIX local) order. Standard and private headers are separated by
a blank line.
Similarly, sort all forward-declarations for structures.

A recent commit made disabling the SMP2P "setup ready" interrupt
unrelated to ipa_modem_stop(). Given that, it seems fitting to get
rid of ipa_modem_init() and ipa_modem_exit() (which are trivial
wrapper functions), and call ipa_smp2p_init() and ipa_smp2p_exit()
directly instead.

The functions ipa_modem_setup() and ipa_modem_teardown() are trivial
wrappers that call ipa_qmi_setup() and ipa_qmi_teardown(). Just
call the QMI functions directly, and get rid of the wrappers.
Improve the documentation of what setting up QMI does.

This patch includes code implementing the modem functionality.
There are several communication paths between the AP and modem,
separate from the main data path provided by IPA. SMP2P provides
primitive messaging and interrupt capability, and QMI allows more
complex out-of-band messaging to occur between entities on the AP
and modem. (SMP2P and QMI support are added by the next patch.)
Management of these (plus the network device implementing the data
path) is done by code within "ipa_modem.c".
Sort of unrelated, this patch also includes the code supporting the
microcontroller CPU present on the IPA. The microcontroller can be
used to implement special handling of packets, but at this time we
don't support that. Still, it is a component that needs to be
initialized, and in the event of a crash we need to do some
synchronization between the AP and the microcontroller.
