cxgb4: move DCB version extern to header file

Move the DCB version string array extern to header file.

Fixes following sparse warning:
cxgb4_dcb.c:13:12: warning: symbol 'dcb_ver_array' was not declared.
Should it be static?

cxgb4: Cleanup macros so they follow the same style and look consistent, part 2

Various patches have ended up changing the style of the symbolic macros/register
defines to different style.

As a result, the current kernel.org files are a mix of different macro styles.
Since this macro/register defines is used by different drivers a
few patch series have ended up adding duplicate macro/register define entries
with different styles. This makes these register define/macro files a complete
mess and we want to make them clean and consistent. This patch cleans up a part
of it.

cxgb4: IEEE fixes for DCBx state machine

* Changes required due to 16eecd9be4b05 ("dcbnl : Fix misleading
dcb_app->priority explanation")
* Driver was previously not aware of what DCBx version was negotiated by
firmware, this could lead to DCB app table in kernel or in firmware being
populated wrong since IEEE/CEE used different formats made clear by above
mentioned commit
* Driver was missing a couple of state transitions that could be caused
by other drivers that use chelsio hardware, resulting in incorrect behaviour
(the change that addresses this also flips the state machine to switch on
state instead of transition, hope this is okay in current window)
* Prio queue info & tsa is no longer thrown away

v2: Print DCBx state transition messages only when debug is enabled
