arm: dts: k3-am69-aquila: Fix SPL USB DFU gadget failures

Around 1 in 20 times, the current R5 SPL fails to pull up the D+ line to
signal that a new USB device (the USB gadget used for downloading the
next stage) joined the bus.

With these strapping options, this is greatly reduced to 1 in thousands.
