[Qemu-riscv] [PULL 38/48] riscv: sifive_u: Change UART node name in devi

From: Bin Meng <address@hidden>

OpenSBI for fu540 does DT fix up (see fu540_modify_dt()) by updating
chosen "stdout-path" to point to "/soc/serial@...", and U-Boot will
use this information to locate the serial node and probe its driver.
However currently we generate the UART node name as "/soc/uart@...",
causing U-Boot fail to find the serial node in DT.
