The old xtensa layer had an unused/untested facility where it would
apparently try to slave a timer tick to an arbitrary interrupt. The
legacy headers were still checking the kconfigs used to enable that
even though nothing wants it and the new driver has removed them,
breaking builds on platforms like S1000 that still use the older
layer.
Don't try to finess this as these files are going away. Just make
them local preprocessor symbols and set them to the default values
they always had.
(Note: the feature doesn't sound like it would have been so bad,
actually. We should probably crib that idea of having an
"external_tick" driver, but there's no reason for it to have been
arch-specific.)
