0553d895f9 Normalize position of header guard
This is the common header guard idiom:

    /*
     * File comment
     */

    #ifndef GUARD_SYMBOL_H
    #define GUARD_SYMBOL_H

    ... actual contents ...

    #endif

A few of our headers have some #include before the guard.
target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard.
A few more have the #define elsewhere.

Change them to match the common idiom.  For spr_def_64.h, that means
dropping #ifndef __DOXYGEN__.  While there, rename guard symbols to
make scripts/clean-header-guards.pl happy.

e8e4994313 cadence_gem: Add support for screening
The Cadence GEM hardware allows incoming data to be 'screened' based on some
register values. Add support for these screens.

We also need to increase the max regs to avoid compilation failures. These new
registers are implemented in the next patch.

step towards that by adding the property to set the queues. At the moment
behaviour doesn't change as we only use queue 0.
