[PATCH v2 12/16] hw/riscv: sifive_u: Avoid using magic number for "riscv

From: Bin Meng
Subject: [PATCH v2 12/16] hw/riscv: sifive_u: Avoid using magic number for "riscv, ndev"
Date: Wed, 7 Dec 2022 18:03:31 +0800

At present magic number is used to create "riscv,ndev" property
in the dtb. Let's use the macro SIFIVE_U_PLIC_NUM_SOURCES that
is used to instantiate the PLIC model instead.
