Please add it to mdss-common.yaml instead

Please keep consistent versioning, so this is new patch in v4.

Your description says nothing new. It's entirely redundant/obvious.
Instead please describe what reserved memory is expected to be here.

mdss-common.yaml didn't like this property at all and
I ran into a lot of new dtbs_check warnings:
https://www.irccloud.com/pastebin/raw/pEYAeaB1

I need some help in decoding these please.

I'm not sure what happened there (and it's hard to understand without
seeing your patch). But after applying your patch to mdss-common.yaml,
`make dt_binding_check' passes:

Yup.. It was my broken patch. I used "For example:" in the property
description and it tripped off the checks. Didn't realise that
casually used ":" can break yaml parsing until now. Sorry for all the
noise.
