platform/x86/intel/ifs: Mark as BROKEN

A recent suggested change to the IFS code has shown that the userspace
API needs a bit more work, see:
https://lore.kernel.org/platform-driver-x86/20220708151938.986530-1-jithu.joseph@intel.com/

Mark it as BROKEN before 5.19 ships, to give ourselves one more
kernel-devel cycle to get the userspace API right.
