arm64: dts: freescale: imx93-phyboard-segin: Add CAN support

Add support for CAN networking on phyBOARD-Segin-i.MX93 via the flexcan1
interface. The CAN PHY chip SN65HVD234D used on the board is compatible
with the TCAN1043 driver using the generic "can-transceiver-phy" and is
capable of up to 1Mbps data rate.
