[PATCH 1/2] powerpc: fix the dependency issue for CRASH_DUMP

[Kevin Hao]

In the current code, the RELOCATABLE will be forcedly enabled when
enabling CRASH_DUMP. But for ppc32, the RELOCABLE also depend on
ADVANCED_OPTIONS and select NONSTATIC_KERNEL. This will cause build
error when CRASH_DUMP=y && ADVANCED_OPTIONS=n. Even there is no such
issue for ppc64, but select is only for non-visible symbols and for
symbols with no dependencies. As for a symbol like RELOCATABLE, it is
definitely not suitable to select it. So choose to depend on it.

Also enable the RELOCATABLE explicitly for the defconfigs which has
CRASH_DUMP enabled.
