ARM: shmobile: Rework EMEV2 scu_base variable
Rename the static scu_base variable into shmobile_scu_base. Later in the series the shmobile_scu_base variable will be made into a global variable so this is preparation only. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
