[PATCH] hangcheck: remove monotomic_clock on x86

John's about to nuke x86's monotonic clock without grepping for it first.  The
patch lamely borrows the ppc64 code for x86.

hangcheck-timer shouldn't be doing it this way

a) HAVE_MONOTONIC should be CONFIG_MONOTONIC_CLOCK and it should be defined
   in arch/xxx/Kconfig.

b) That ifdef tangle shouldn't be in hangcheck-timer.c.  It should be using
   arch-provided helper functions, which CONFIG_MONOTONIC_CLOCK-enabling
   architectures implement in arch/something.c
