ARM: dts: msm: update USB attributes for mdmfermium

Add QDSS dt node as subnode of USB dt node, also correct
the interrupt number for async interrupt.

As fermium does not have snoc clock, pass rate for snoc
as 0 so drivers handles this appropriately. Also add id
detection gpio and  interrupt thereshold value.
