[PATCH] riscv: dts: starfive: fml13v01: enable pcie1
From: Sandie Cao
Date: Fri Feb 07 2025 - 04:54:51 EST
Starfive Soc common defines GPIO28 as pcie1 reset, GPIO21 as pcie1 wakeup;
But the FML13V01 board uses GPIO21 as pcie1 reset, GPIO28 as pcie1 wakeup;
redefine pcie1 gpio and enable pcie1 for pcie based Wi-Fi.
