arm64: dts: ti: k3-am625-sk: Add support for USB
AM62 SoC has two instances of USB and they are brought on to the board
in the following way,
-> USB0 instance
- This is brought out to a USB TypeC connector on board through TPS6598 PD
controller. The PD controller should decide the role based on CC pin in
the connector. Unfortunately the irq line for the TPS isn't hooked up
which is a mode not yet support by the driver (some patches were
submitted earlier this year[0]). So for now the PD controller is left
out and peripheral mode chosen.
-> USB1 instance
- This is brought out to a USB TypeA connector on board.
Therefore, add the required device tree support for the above in the board
dts file.
