Subject: [PATCH 0/4] DW DMAC: update device tree

It wasn't possible to enable some features like
memory-to-memory transfers or multi block transfers via DT.
It is fixed by these patches.

 * Rename is_private to is-private as ordered by DT policy.
 (just for cleanup) The change leaves the support for the 
 old format.

 * Add is-memcpu property, so it is possible to
 enable memory-to-memory transfers support via DT.

 * Add hw-llp property, so it is possible to enable
 hardware multi block transfers support via DT.

 * Update DW DMAC device tree documentation.
