fbdev: matrox: fix -Wextra build warnings 

When 'DEBUG' is not defined, modify the dprintk() macro to use the
no_printk() macro instead of using <empty>.
This fixes build warnings when -Wextra is used and provides
printk format checking:

../drivers/video/fbdev/matrox/matroxfb_base.c:635:77: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
../drivers/video/fbdev/matrox/matroxfb_Ti3026.c:632:54: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
../drivers/video/fbdev/matrox/matroxfb_Ti3026.c:654:53: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
