[PATCH 10/43] ARM: shmobile: Kill off sh73a0 scu_base_addr() function

[Simon Horman <horms+renesas@verge.net.au>]

From: Magnus Damm <damm@opensource.se>

Replace scu_base_addr() with a static shmobile_scu_base
variable and introduce SH73A0_SCU_BASE.

Later in the series the shmobile_scu_base variable will be
made into a global variable so this is preparation only.
