D2500CC which I have, syscons in text-mode fails to show the expected
contents due to write errors into video-memory.
At least one of the causes is that we copy from syscons internal buffer
to the video memory with optimized bcopy(9) which uses >16bit operations.
Until now, 32bit and wider operations have always worked on the video
memory, but since I cannot find a single source which says that this
SHALL work, and since these chipsets/bugs are now out there, this
commit changes syscons to always use 16bit copies on i386 & amd64.
This may be relevevant for PR's:

and various other bug reports floating elsewhere on the net, but
I lack hardware to test those.
Due to some differences in MSRs between Xeon Sandy Bridge and Core Sandy
Bridge (Model 0x2A), wrmsr() may generate in a GP# fault exception and so a
panic of the machine.

* Add an OS_A_REG_WRITE() routine - analog writes require a 100usec delay
on AR9280 and later, so create a method to do it.
* Use it for the AR9287 analog writes.
* Re-indent and style(9) the code.
This just requires a little HAL change (add a new config parameter) and
some glue in if_ath_pci.c, however I'm leaving this up for someone else
to do.

layer, but it is read directly by the MI VM layer. This change introduces
pmap_page_is_write_mapped() in order to completely encapsulate all direct
access to PGA_WRITEABLE in the pmap layer.
Aesthetics aside, I am making this change because amd64 will likely begin
using an alternative method to track write mappings, and having
pmap_page_is_write_mapped() in place allows me to make such a change
without further modification to the MI VM layer.
As an added bonus, tidy up some nearby comments concerning page flags.
