ARM: dts: msm: Use "iommu-addresses" property for parrot dwc3

Browse Source 
Use upstream compatible DT property "iommu-addresses" instead
of "qcom,iommu-dma-addr-pool" for dwc3 which describes the
addresses that dwc3 cannot use.
Extend the address and size cells to ensure that IOMMU returns
a 32 bit address, in order to define a region that will block
0xf0000000--0xffffffffffffffff.
