[PATCH] ppc64: compile nls_cp437 and nls_iso8859_1 into the kernel in defconfig

compile nls_cp437 and nls_iso8859_1 into the kernel in defconfig.  This is
already enabled in pSeries_defconfig.

Reason: if one just boots the new shiny zImage and the root filesystem is
on a filesystem not readable by yaboot (like jfs, raid or lvm) upgrading
the bootloader will fail because the FAT bootpartition can not be mounted.
