riscv: ftrace: Make function graph use ftrace directly
Similar to commit 0c0593b45c9b ("x86/ftrace: Make function graph use
ftrace directly") and commit c4a0ebf87ceb ("arm64/ftrace: Make
function graph use ftrace directly"), RISC-V has no need for a special
graph tracer hook. The graph_ops::func function can be used to install
the return_hooker.
This cleanup only changes the FTRACE_WITH_REGS implementation, leaving
the mcount-based implementation is unaffected.
Perform the simplification, and also cleanup the register save/restore
macros.
