* boot/i386/pc/boot.S: Remove root_drive.  Assert offset of
	boot_drive_check by using GRUB_BOOT_MACHINE_DRIVE_CHECK.  Don't
	save %dx, we only need %dl and we never change it.
	* boot/i386/pc/cdboot.S: Don't set the root drive.
	* boot/i386/pc/pxeboot.S: Likewise.
	* include/grub/i386/pc/boot.h: Remove
	GRUB_BOOT_MACHINE_ROOT_DRIVE, adjust
	GRUB_BOOT_MACHINE_DRIVE_CHECK.
	* include/grub/i386/pc/kernel.h: Remove grub_root_drive.
	* kern/i386/pc/init.c (make_install_device): Remove references
	to grub_root_drive.
	* kern/i386/pc/startup.S: Likewise.
	* util/i386/pc/grub-setup.c (setup): Don't set root_drive.
