[PATCH] ppc64: change duplicate Kconfig menu "General setup" to "Bus Options"

arch/ppc64/Kconfig defines a "General setup" menu, but also sources
init/Kconfig which also defines a "General setup" menu.  Both of these
menus appear at the top level of make menuconfig.  Having two menus with
the same name is confusing.  This patch renames the ppc64/Kconfig menu to
be "Bus Options" and moves options in this menu which are not bus related
to the end of the "Platform support" menu.

There are many variations among architectures on the exact naming of the
"Bus Options" menu.  I chose to use the simplest one, which is also used
in arch/ppc/Kconfig.
