I found one more missing dependency in the new driver: when building
without CONFIG_PCI_IOV, pci_sriov_configure_simple() cannot be
called directly:

drivers/misc/mrvl_cn10k_dpi.c: In function 'dpi_remove':
include/linux/stddef.h:9:14: error: called object is not a function or function pointer
    9 | #define NULL ((void *)0)
      |              ^
include/linux/pci.h:2416:41: note: in expansion of macro 'NULL'
 2416 | #define pci_sriov_configure_simple      NULL
      |                                         ^~~~
drivers/misc/mrvl_cn10k_dpi.c:652:9: note: in expansion of macro 'pci_sriov_configure_simple'
  652 |         pci_sriov_configure_simple(pdev, 0);

Add this to the Kconfig file as well.

Fixes: 5f67eef6 ("misc: mrvl-cn10k-dpi: add Octeon CN10K DPI administrative driver")
