Hi,
The core DT schema defines generic 'dma-channels' and 'dma-requests'
properties, so in preparation to moving bindings to DT schema, convert
existing users of '#dma-channels' and '#dma-requests' to the generic
variant.
Not tested on hardware.
IMPORTANT
=========
The patchset is not bisectable! The DTS patch should be applied a
release *after* driver change is accepted.

The generic property, used in most of the drivers and defined in generic
dma-common DT bindings, is 'dma-channels'.

Sorry for the mess, but I missed here one patch.
