When running RISC-V QEMU with the Bochs device attached via PCIe the probe of the Bochs device fails with: [drm:bochs_hw_init] *ERROR* ID mismatch
This was introduced by this commit: 7780eb9ce8 bochs: convert to drm_dev_register
To fix the error we ensure that pci_enable_device() is called before bochs_load().
