[PATCH v5 13/13] powerpc/ptrace: move ptrace_triggered() into hw_breakpoint.c

[Christophe Leroy]

ptrace_triggered() is declared in asm/hw_breakpoint.h and
only needed when CONFIG_HW_BREAKPOINT is set, so move it
into hw_breakpoint.c

Signed-off-by: Christophe Leroy <christophe.leroy@xxxxxx>
---
v4: removing inclusing of hw_breakpoint.h now. Previously it was done too early.
