drm/bochs: Fix the ID mismatch error
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().
Fixes: 7780eb9ce80f ("bochs: convert to drm_dev_register")
