Pl330 integrated in rk3288 platform doesn't support
DMAFLUSHP function. So we add broken-no-flushp quirk
for it.

Changes in v1:
- rename broken-no-flushp to "arm,pl330-broken-no-flushp" suggested
  by Krzysztof.
- remove Sunny's tag

Looks like you just added the "From" here.  I think that's fine, but
better to set the author so you get the right cover letter...

Note that typically for patches I see people go from "no v" to "v2".  AKA:
* PATCH
* PATCH v2
* PATCH v3

Note that you should add bindings _before_ the usage of them.  So
patch #5 (Documentation) needs to come before this one.

Other than the small nits above, this looks fine to me.

Cool! That makes sense.
Thanks, Doug.
