This patch adds an initial AHB-to-IP TrustZone (AIPS-TZ) initialization routine. Setting up the AIPSTZ controller is required to inform the SoC interconnect fabric which bus-masters can read/write and if the read/writes are buffered. For our purposes the initial configuration is for everything to be open. We can lock-down later on as necessary. Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
