ARM: restart: ixp23xx: use new restart hook
Hook these platforms restart code into the new restart hook rather than using arch_reset(). In doing so, we split out the ixdp2351 restart code into its own platform file. Acked-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
