arm64: dts: ti: k3-am625-verdin: Enable Verdin UART2

Enable UART2 for AM62 based SOM's Verdin carrier boards Dahlia,
Development and Yavia.

Earlier Verdin UART2 was reserved by R5 DM firmware which can be now
configured using boardcfg during U-boot compilation. In a default
config, no one writes to this UART.
