dmaengine: axi-dmac: move active_descs list init after device-tree init

Browse source 
We want to enable the clock right after it is obtained. Then later we'll
want to read the core version via register-access (which requires the clock
to be enabled).

The initialization of the active_descs list can be postponed after reading
from registers (or reading the device-tree).
