zynqmp: Put pm_secure_lock in coherent memory region
DEFINE_BAKERY_LOCK() macro is used to put lock in coherent memory region.
ARM Trusted Firmware design guide, chapter 11 states that bakery_lock data
structures should be allocated in coherent memory region because it is
accessed by multiple CPUs with mismatched shareability, cacheability and
memory attributes.
