[Arm-netbook] HDMI High-Frequency Layout: Recommendations

For recommended wiggle dimensions consult Toradex, p. 22, figure 23,
(reproduced below for convenience of discussion):

Here s = spacing between traces of a differential pair = 5mil (for our layout)
w = width of traces in differential pair = 5mil (for our layout)

Hence, Toradex suggests deviating away no more than 10mil and staying
at that distance no more than 15mil.  I would suggest spending less
distance away, say 7.5mil before turning back so that we get more
length at a 45 degree angle with the other trace which is where we
make up path length.
