ftrace: Allow WITH_ARGS flavour of graph tracer with shadow call stack
The recent switch on arm64 from DYNAMIC_FTRACE_WITH_REGS to
DYNAMIC_FTRACE_WITH_ARGS failed to take into account that we currently
require the former in order to allow the function graph tracer to be
enabled in combination with shadow call stacks. This means that this is
no longer permitted at all, in spite of the fact that either flavour of
ftrace works perfectly fine in this combination.
So permit WITH_ARGS as well as WITH_REGS.
Fixes: ddc9863e9e90 ("scs: Disable when function graph tracing is enabled")
