riscv: fgraph: Select HAVE_FUNCTION_GRAPH_TRACER depends on HAVE_DYNAMIC_FTRACE_WITH_ARGS 



Currently, fgraph on riscv relies on the infrastructure of
DYNAMIC_FTRACE_WITH_ARGS. However, DYNAMIC_FTRACE_WITH_ARGS may be
turned off on riscv, which will cause the enabled fgraph to be abnormal.
Therefore, let's select HAVE_FUNCTION_GRAPH_TRACER depends on
HAVE_DYNAMIC_FTRACE_WITH_ARGS.

Fixes: a3ed4157 ("fgraph: Replace fgraph_ret_regs with ftrace_regs")
