usb: dwc3: qcom: add URS Host support for sdm845 ACPI boot

BugLink: https://bugs.launchpad.net/bugs/1919492
commit c25c210f590e7a37eecd865d84f97d1f40e39786 upstream.

For sdm845 ACPI boot, the URS (USB Role Switch) node in ACPI DSDT table
holds the memory resource, while interrupt resources reside in the child
nodes USB0 and UFN0.  It adds USB0 host support by probing URS node,
creating platform device for USB0 node, and then retrieve interrupt
resources from USB0 platform device.
