[POWERPC] Fix compilation for CONFIG_DEBUGGER=n and CONFIG_KEXEC=y 

Looks like "[POWERPC] kdump shutdown hook support" broke builds when
CONFIG_DEBUGGER=n and CONFIG_KEXEC=y, such as in g5_defconfig:

arch/powerpc/kernel/crash.c: In function 'default_machine_crash_shutdown':
arch/powerpc/kernel/crash.c:388: error: '__debugger_fault_handler' undeclared (first use in this function)
arch/powerpc/kernel/crash.c:388: error: (Each undeclared identifier is reported only once
arch/powerpc/kernel/crash.c:388: error: for each function it appears in.)

Move the debugger hooks to under CONFIG_DEBUGGER || CONFIG_KEXEC, since
that's when the crash code is enabled.

(I should have caught this with my build-script pre-merge, my bad. :( )
