USB4 device node which is defined in [1] is redefined in here
causing boot failures. Remove the duplicated entry and instead extend it
with child node info through corresponding label reference.

Gowtham,
It is preferable to reference the commit SHA instead of line number references
like above (they will change). Please also use a Fixes: for this, so it can be
applied onto stable kernels as well.

Tony,

This can be fixed in couple of different ways, and I see there have been
different commits that have ultimately caused this.
 6b14eb4705d6 ("ARM: dts: DRA7: Move USB_OTG 4 to dra74x.dtsi")
 549fce068a31 ("ARM: dts: dra7: Add l4 interconnect hierarchy and ti-sysc data"
 bcbb63b80284 (ARM: dts: dra7: Separate AM57 dtsi files")
 c7b72abca61e ("ARM: OMAP2+: Drop legacy platform data for dra7 dwc3")

Would you prefer that we just drop the USB4 target-module reference in
dra7-l4.dtsi following the first commit?

regards
Suman
