Yuho Choi 4aa8110000 drm/sysfb: ofdrm: fix PCI device reference leaks 
display_get_pci_dev_of() gets a referenced PCI device via
pci_get_device(). Drop that reference when pci_enable_device() fails and
release it during the managed teardown path after pci_disable_device().

Without that, ofdrm leaks the pci_dev reference on both the error path
and the normal cleanup path.

Fixes: c8a17756c4 ("drm/ofdrm: Add ofdrm for Open Firmware framebuffers")
