dts: Increase default coherent pool size 

dwc_otg allocates DMA-coherent buffers in atomic context for misaligned
transfer buffers. The pool that these allocations come from is set up
at boot-time but can be overridden by a commandline parameter -
increase this for now to prevent failures seen on 4.19 with multiple
USB Ethernet devices.
