Kconfig: Temporarily disable HAVE_HW_BREAKPOINT feature flag 

Recent 8660 bootup failures on the .38 kernel have been traced to
changes in hw_breakpoint.c that occasionally trigger a debug_event
on bootup, invoking a preconfigured hardware breakpoint which causes
the Scorpion cores to halt execution. This prevents the target from
booting successfully, and the exact cause of these debug events is
not yet known.

This patch simply disables hardware breakpoint support for the time
being; this is only meant to be a stopgap measure to unblock
automation testing.

This is done by manually disabling the HAVE_HW_BREAKPOINTS feature
flag in the Kconfig. Currently there is no Kconfig menu option to
disable this flag in a "clean" way without also disabling PERF_EVENTS
(this is still needed for performance profiling).
