sched/clock: Add dummy clear_sched_clock_stable() stub function
In commit:
acb04058de494 ("sched/clock: Fix hotplug crash")
the PARISC code gained a call to this function.
However the prototype for it is within a CONFIG_HAVE_UNSTABLE_SCHED_CLOCK=y
#ifdef/#endif. That, combined with this:
arch/parisc/Kconfig: select HAVE_UNSTABLE_SCHED_CLOCK if SMP
means that PARISC can have it either enabled or disabled, resulting
in the following build fail:
arch/parisc/kernel/setup.c:180:2: error: implicit declaration of
function 'clear_sched_clock_stable' [-Werror=implicit-function-declaration]
Add a no-op stub for the non-SMP case to prevent this.
