dmaengine: at_xdmac: get the number of DMA channels from device tree
In case of kernel runs in non-secure mode, the number of DMA channels can
be got from device tree since the value read from GTYPE register is "0" as
it's always secured.
As the number of channels can never be negative, update them to the type
"unsigned".
This is required for LAN969x.
