Currently, wait_for_device_probe api added before dwc3_probe
is called in core_init which is suppose to ensure that in case
the child is getting teared down, the userspace doesn't get to
write UDC and do gadget_start.
However, wait_for_device_probe api makes sure that the driver wait
until all probes are completed. Ideally, it wouldn't be a problem
but in cases of other driver's probe fails, usb would be affected
here even though usb isn't at fault.
Fix this by making a dummy-dependency on smmu node since the original
intention of the patch was to make sure if smmu driver was probed
successfully, then only proceed for child driver's probe.

DWC3 host and XHCI plat now communicates the maximum number of interrupters
the XHCI HCD will allocate. Since platforms only require a limited number
of interrupters (i.e. 3) make sure XHCI doesn't allocate more than is
required.

In order to ensure that IOMMU returns a 32 bit address, extend the
address and size cells to 2, in order to define a region that will
block 0xf0000000--0xffffffffffffffff. By increasing the address and
size cells for the parent node, the DWC3 child node has to also
change the 'reg' entry to accommodate the added values.

Use upstream compatible device smmu address space DT property
"iommu-addresses" in accordance to FR92369. Replace existing use of
"qcom,iommu-dma-addr-pool" with "iommu-addresses" for dwc3 node in usb0
for describing to the DMA API what IOVA addresses dwc3 cannot use.
