ARM: ls102xa: allow all the peripheral access permission as R/W.

The Central Security Unit (CSU) allows secure world software to
change the default access control policies of peripherals/bus
slaves, determining which bus masters may access them. This
allows peripherals to be separated into distinct security domains.
Combined with SMMU configuration of the system masters privileges,
these features provide protection against indirect unauthorized
access to data.

For now we configure all the peripheral access permissions as R/W.
