	(main): Call `grub_pc_partition_map_init',
	`grub_amiga_partition_map_init' and
	`grub_apple_partition_map_init' and deinitialize afterwards.
	* util/i386/pc/biosdisk.c: Include `#include
	<grub/partition.h>' and `include <grub/pc_partition.h>' instead of
	`<grub/machine/partition.h>'.
	* util/i386/pc/grub-setup.c: Likewise.
	* util/i386/pc/biosdisk.c: Likewise.
	(grub_util_biosdisk_get_grub_dev): Only access the PC specific
