[PATCH] SH: fix kconfig unmet dependency warning for FRAME_POINTER

[Randy Dunlap]

FRAME_POINTER depends on DEBUG_KERNEL so DWARF_UNWINDER should
depend on DEBUG_KERNEL before selecting FRAME_POINTER.

WARNING: unmet direct dependencies detected for FRAME_POINTER
  Depends on [n]: DEBUG_KERNEL [=n] && (M68K || UML || SUPERH [=y]) || ARCH_WANT_FRAME_POINTERS [=n]
  Selected by [y]:
  - DWARF_UNWINDER [=y]

Fixes: bd353861c735 ("sh: dwarf unwinder support.")
