This patch re-factors goya_parse_cb_no_ext_queue() to make it more
readable by inverting the check inside the first if statement so the bulk
of the function won't be inside an if statement.

The patch also fixes a spelling error in the name of the function.

pr_fmt() should be defined before including linux/printk.h, either
directly or indirectly, in order to avoid redefinition of the macro.
Currently the macro definition is in habanalabs.h, which is included in
many files, and that makes the addition/reorder of includes to be prone
to compilation errors.
This patch cancels this dependency by defining the macro only in the few
source files that use it.

Since CoreSight hardware topology can use a 'hidden' funnel in the
trace data path, this kind funnel doesn't have register for accessing
and is used by default from hardware design perspective.  Below is an
example for related hardware topology:

  +------+  +------+
  | cpu0 |->| ETM  |-\
  +------+  +------+  \-> +--------+  +-----+
   ......                 | Funnel |->| ETF |-\    Hidden funnel
  +------+  +------+  /-> +--------+  +-----+  \        |
  | cpu3 |->| ETM  |-/                          \       V
  +------+  +------+                             \-> +--------+
                                                     | Funnel |-> ...
  +------+  +------+                             /-> +--------+
  | cpu4 |->| ETM  |-\                          /
  +------+  +------+  \-> +--------+  +-----+  /
   ......                 | Funnel |->| ETF |-/
  +------+  +------+  /-> +--------+  +-----+
  | cpu7 |->| ETM  |-/
  +------+  +------+

The CoreSight funnel driver only supports dynamic funnel with
registration register resource, thus it cannot support for the static
funnel case and it's impossible to create trace data path for this case.

This patch is to extend CoreSight funnel driver to support both for
static funnel and dynamic funnel.  For the dynamic funnel it reuses the
code existed in the driver, for static funnel the driver will support
device probe if without providing register resource and the driver skips
registers accessing when detect the register base is NULL.

Following the same fashion with replicator DT binding, this patch is to
unify the DT binding for funnel to support static and dynamic modes;
finally we get the funnel DT binding as below:

Before patch:

  Static funnel, aka. non-configurable funnel:
    Not supported;

  Dynamic funnel, aka. configurable funnel:
    "arm,coresight-funnel", "arm,primecell";

After patch:

  Static funnel:
    "arm,coresight-static-funnel";

  Dynamic funnel:
    "arm,coresight-dynamic-funnel", "arm,primecell";
    "arm,coresight-funnel", "arm,primecell"; (obsolete)

At the end of this patch, it gives an example for static funnel DT
binding, and updates the dynamic funnel example.

CoreSight uses below bindings for replicator:

  Dynamic replicator, aka. configurable replicator:
    "arm,coresight-dynamic-replicator", "arm,primecell";

  Static replicator, aka. non-configurable replicator:
    "arm,coresight-replicator";

The compatible string "arm,coresight-replicator" is not an explicit
naming to express the replicator is 'static'.  To unify the naming
convention, this patch introduces a new compatible string
"arm,coresight-static-replicator" for the static replicator; the
compatible string "arm,coresight-replicator" is kept for backward
compatibility, but tag it as obsolete and suggest to use the new
compatible string.

As result CoreSight replicator have below bindings:

  Dynamic replicator:
    "arm,coresight-dynamic-replicator", "arm,primecell";

  Static replicator:
    "arm,coresight-static-replicator";
    "arm,coresight-replicator"; (obsolete)
