From: Will Deacon <will.deacon@arm.com>
Subject: Kconfig: remove HAVE_LATENCYTOP_SUPPORT

As illustrated by a3afe70b83fd ("[S390] latencytop s390 support."),
HAVE_LATENCYTOP_SUPPORT is defined by an architecture to advertise an
implementation of save_stack_trace_tsk.

However, as of 9212ddb5eada ("stacktrace: provide save_stack_trace_tsk()
weak alias") a dummy implementation is provided if STACKTRACE=y.  Given
that LATENCYTOP already depends on STACKTRACE_SUPPORT and selects
STACKTRACE, we can remove HAVE_LATENCYTOP_SUPPORT altogether.
