All the timeout values fit in u16, so let's shrink the structure
a bit.

This ends up actually increasing the .text size a bit due to
some changes in instructions (constant imul+small jmps replaced
with mov+bigger jmpqs). Seems pretty arbitrary to me so I'll
just pretend I didn't see it.

    text	   data	    bss	    dec	    hex	filename
-  34521	    360	      0	  34881	   8841	intel_hdmi.o
+  34537	    360	      0	  34897	   8851	intel_hdmi.o

Looks Good to me.
