While starting a port for the A13-based TZX-Q8-713B7 tablet, it appears
that my LCD cable also has the Netron-DY E231732 marking, but is
definitely different from the one on the SinA33. So I think Chen-Yu's
comment was founded and "Netron DY E231732" does not reflect the panel
name.

Here are some details regarding the LCD cable on both devices:

The SinA33 has a 1024x600 panel with the following markings:
7300101463
E231732
NETRON-DY <> 1
94V-0\1310

The TZX-Q8-713B7 has a 800x480 panel with the following markings:
7300101448
E231732
NETRON-DY <> 2
94V-0\1249

So it seems that the distinctive part of the name is
7300101463/7300101448.

Also, it seems that various online shops list the panels with a name
like "E231732 7300101463". So maybe we could change the bindings to
have:

- netron-dy,e231732-7300101463
- netron-dy,e231732-7300101448

What do you think? Does that make sense?

We should probably also fallback netron-dy,e231732 to the sina33's panel
in order to avoid breaking the ABI.
