configs: starfive: Enable PCIE auto enum and NVME/USB stuff for Starfive Visionfive 2

Although PCIE driver already exists, board defconfig isn't configured to
enable PCIE enum on boot, thus USB storage device and NVME drive are not
supported by default. So modify defconfig to enable PCIE auto enum, then
start USB subsystem and scan nvme drive on boot.
