[PATCH] rfc v3: ARM: mach-shmobile: mackerel: Add zboot support

When CONFIG_ZBOOT_ROM is selected, the resulting zImage file will be small
boot loader and may be burned to rom or flash.

Compile tested only.

This patch assumes that head-mackerel.txt will be the same as head-ap4evb.txt.
I am waiting for verification of this.

This patch depends on
* ARM: 6515/1: Add zboot support for SuperH Mobile ARM
  (merged into the devel branch of Russel King's linux-2.6-arm tree)
* ARM: 6514/1: mach-shmobile: Add zboot support for SuperH Mobile ARM
  (merged into the devel branch of Russel King's linux-2.6-arm tree)
* MACH_MACKEREL (3211) being present in arch/arm/tools/mach-types

v2:
* Use head-mackerel.txt for Mackerel.
  head-ap4evb.txt was used by mistake.

v3:
* Actually make the change to use head-mackerel.txt
