arm64: dts: imx95-19x19-evk: correct the phy setting for flexcan1/2 

1, the phy support up to 8Mbit/s databitrate for CAN FD.
   refer to product data sheet:
     https://www.nxp.com/docs/en/data-sheet/TJA1463.pdf


2, the standby pin of the phy is ACTIVE_LOW.
3, the phy of flexcan2 connect the standby/en pin to PCAL6408 on i2c4 bus.
