I'm actually not sure what to do here: if this enum is meant to be
used by userspace, then it has to be the same regardless of kernel
configuration.  One option would be to have the kernel expose all the
values to userspace and then map them internally if
CONFIG_HAVE_MIXED_BREAKPOINT_REGS isn't set, but that feels like it'd
be more invasive.

Here I took the simple and fail-fast route to hide all the
definitions.

This should be in include/linux/hw_breakpoint.h without __KERNEL__ markings.
