The .read_2_2() hooks is never called for any of the message
types with a zero timeout. So it's all just dead weight which
we can chuck.

    text	   data	    bss	    dec	    hex	filename
-  34701	    360	      0	  35061	   88f5	intel_hdmi.o
+  34633	    360	      0	  34993	   88b1	intel_hdmi.o

Timeout is added for supporting msgs read. These msgs with 0 timeout
are only written. Hence can be removed from the timeout table.
