Commit e9d6b3358ac35901ccc6a4a5a317670fa469db25 adds common APIs to
get scu base address from CP15. This patch series connverts some platforms
to use that interface.

arm: highbank: make use of common scu_a9_get_base() interface
arm: imx: make use of common scu_a9_get_base() interface
arm: prima2: make use of common scu_a9_get_base() interface
arm: socfgpa: make use of common scu_a9_get_base() interface

Make use of common scu_a9_get_base() and delete the comment since the
interface is self commented.
