media: intel/ipu6: Fix some redundant resources freeing in ipu6_pci_remove()

pcim_iomap_regions() and pcim_enable_device() are used in the probe. So
the corresponding managed resources don't need to be freed explicitly in
the remove function.

Remove the incorrect pci_release_regions() and pci_disable_device() calls.
