'default N' should be 'default n', though they happen to have the same
effect here, due to undefined symbols (N in this case) evaluating to n
in a tristate sense.

Remove the default from VMD instead of changing it. bool and tristate
symbols implicitly default to n.

Discovered with the
https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py
script.

The PCIE_ALTERA symbol in this file also depends on the globally
undefined symbol OF_PCI, which was removed in 4670d610d592 ("PCI: Move
OF-related PCI functions into PCI core").

Cheers,

In the title, please include a clue about what default you're talking
about, e.g., mention Kconfig somehow.
