Add the rmtfs-mem node which was part of one of the "unknown" memory
reservation. Split that one, make sure the reserved-memory in total
still covers the same space.

Could you please test dynamic rmtfs alloc, which should be possible
on some (most?) boards after 9265bc6bce6919c771970e5a425a66551a1c78a0?

To be honest, I'd like to not continue to experiment with reserved-memory on 
this board, I've already spent way too much time figuring out how to not make 
the phone crash under some circumstances, and now it seems relatively stable.
I might've even put my eMMC into some weird read-only mode where any write to 
it just weirdly fails (also original software) by writing to random locations 
in the RAM (or well, what Linux thought was non-special RAM).

Luca
