mb/google/nissa/var/nivviks: Enable ISH when UFS is present

In order to enable the UFS controller (PCI device 12.7), the PCI
specification says that the device at function 0 in the same slot must
also be enabled, which is the ISH. Therefore, enable ISH when UFS is
present.

For more context on why this is necessary, see CB:62662 which enabled
UFS and ISH for adlrvp_n.

BUG=b:234136500
TEST=Build test. Will test that UFS works once we have hardware.
