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.

All of the config data files and all of the register definition
files (plus a few others) use GSI_EE_AP, which is defined in
"ipa_version.h".  Include that header where it's needed.

All of the IPA register definition files include "../ipa.h", though
none of them need anything defined there.  Similarly, all of the GSI
register definition files include "../gsi.h", but don't need anything
defined there.  Remove these unnneded includes.

All of the configuration data files include "../gsi.h", though none
of them need anything defined there, so remove these includes.

Remove other includes of local header files that are not required.

Include "ipa_gsi.h" in "ipa_gsi.c", so the public functions are
defined before they are used in "ipa_gsi.c".  This addresses some
warnings that are reported with a "W=1" build.

This patch provides interface functions supplied by the IPA layer
that are called from the GSI layer.  One function is called when a
GSI transaction has completed.  The others allow the GSI layer to
inform the IPA layer when the hardware has been told it has new TREs
to execute, and when the hardware has indicated transactions have
completed.
