I suggest make this more human-readable instead of replicating the
machine-readable data of HWDB.

My proposal here:

```
The Nuvoton MA35D1 chip contains a DCUltraLite display controller with
model number 0x0 (sic, the model name contains no number either),
revision 0x5560 and customer ID 0x305. It has a similar register map
with DC8000, only one display output and only 32x32 cursor supported.
```

It's a little ambiguous that "last" here means whether the last in the
patchset or the last in the HWDB array, although I think it's not so
needed to explain the reason of the place in the patchset.

I propose just say `Adding it to the HWDB to enable it to be usable
with the verisilicon driver.` .
