ARM: shmobile: Remove old SCU boot code
Remove shmobile_secondary_vector_scu now when all SCU enabled SMP platforms instead make use of shmobile_boot_scu. This removes two inline virtual to physical address conversions. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
